Fresh, clean clothes help us live our best lives—thanks to the 200,000 U.S. workers who keep local laundromats running. Although they deal with grueling shifts and sporadic tips, there are some perks to handling strangers’ intimates all day: Laundromats often double as meaningful community spaces, and the steady demand keeps business stable. Mental Floss interviewed three workers in the industry to learn about what the job is really like, from the things you probably do that make them wince to the most bizarre items customers have left in pockets.

1. THEY WISH YOU'D TIP.

Laundry workers earn an average of $23,770 a year nationwide to wash your mismatched socks. But Pilar Flores, a laundry worker in Queens, New York, says "not a lot of people tip." At the laundromat where she works, a mason jar of dollar bills sits strategically next to the cash register, even though it doesn't see much action.

However, Jessica Steier, a laundry owner and operator in California, says she noticed a bump in tips when card payment and apps became an option for transactions, instead of just cash. (Her business uses the app Rinse, which works like Seamless, but for clothes.) Thanks to this technology, customers have fewer excuses to skip the gratuity. “I feel like they feel a little guilty if they don’t,” Steier says.

2. THEY MIGHT HAVE TO DO 300 POUNDS OF LAUNDRY IN ONE MORNING.

“You’re constantly dealing with issues, jumping from task to task, on your feet for 8-hour shifts," Steier says. Flores, who works seven hours a day, seven days a week, says she has to wash between 250 and 300 pounds of laundry in the morning shift just to keep up with next-day demand. With such a tight turnaround, breaks aren’t common. “The only breaks we get is when it’s not crazy,” says Flores. “It’s always busy. I can’t even sit here for five minutes.”

3. THEY'VE FOUND SURGICAL EQUIPMENT IN PEOPLE'S POCKETS.

Careless customers can create a real headache for the people doing their laundry. “Sometimes, especially women, they’ll leave their lipstick and it will mess up all their laundry,” Flores says. Kids are culprits, too, she adds—they leave crayons in their pockets, which can melt in the high heat and stick to fabric, not to mention the machine.

And while staining is a big source of stress, sometimes there’s little the laundromat worker can do. “We try to rewash it, but if we see it doesn’t come out, it’s not in our hands, it’s not our responsibility,” Flores says. “It’s the customer’s responsibility.”

Laundromat workers also often find spare change—but it’s not theirs to keep. “I once found over $60 in a guy’s pockets, and he was absolutely astonished that we gave it back,” laundromat employee Mehunno shared on a Reddit AMA. Other discoveries may be bizarre: “We do laundry for a few doctors, so I’ve found surgical equipment before,” Mehunno writes. “Found a car’s registration, pocket knife, and this guy’s wedding ring three separate times.”

4. THE WORK CAN ENDANGER THEIR HEALTH.

Some surprises workers find in the laundry aren't just odd, but downright dangerous. "We have seen used preservatives, bloodied sanitary pads, dirty baby diapers and even vomit," laundry worker Daysi Raimundo from Astoria, Queens, told Voices of NY. Besides being gross, bodily fluids like blood can harbor bacteria such as E. coli and salmonella—especially problematic since many laundromat workers don't have health insurance, as Rosanna Rodríguez-Aran of the New York-based Laundry Workers Center told Voices of NY. The U.S. Department of Labor’s Occupational Safety and Health Administration has detailed information about how to handle contaminated laundry, but many workers just do the best they can. Based on complaints received at the LWC offices, many laundry workers suffer from problems such as back pain, rashes, skin problems, and respiratory problems, caused in part by repeated exposure to cleaning chemicals.

5. ECONOMIC SLUMPS DON'T STRESS THEM OUT.

“In the recession, a lot of people tried to cut back on expenses,” Steier says. “But everyone has to have clean clothes. So it’s recession-proof. You gotta do your laundry.” In fact, the Coin Laundry Association has found that coin-operated laundries thrive in periods of both growth and recession. And as home ownership decreases nationwide, people depend more on outside laundry facilities, according to the association’s website.

According to Steier, California’s droughts have also helped bump up business: When water bills soar for homeowners, customers flock to laundromats instead.

6. THEY HAVE CRAZY WATER BILLS.

It's not unusual for laundromat water bills to average several thousand dollars a month, which can make it hard to keep costs down for consumers. (In 2013, one laundromat in Maryland said it would need to raise prices 565 percent to keep up with their $6000 water bill.)

Joon Sohn, who's run a coin-operated laundromat for a decade in Lakewood, New Jersey, says his water bill comes to around $2000 per month, which he says is forcing him to think about selling his business. Ideally, utilities should only amount to about 20-25% of the gross self-service income from a laundromat, experts say—but older machines and changes in local water prices can make it hard to hit that target.

7. THEY'RE SCRUPULOUS ABOUT CLEANING THE LINT TRAY.

“We clean out lint trays every day,” Steier says. “They can cause lint fires.” That's not just a concern at commercial laundromats, either: The National Fire Protection Association found that municipal fire departments responded to home fires involving clothes dryers and washing machines nearly 16,000 times a year between 2010-2014 [PDF]. Dust, fiber, or lint were the leading causes of these flare-ups.

Frequent cleaning of the lint tray can also help keep utility costs low. That's because dryers don’t work at maximum efficiency when lint trays are full, Steier explains.

8. THEY WINCE WHEN YOU ADD SOAP TOO EARLY.

Ever stared at the soap compartments atop a washing machine, wavering over when to add detergent? You’re not alone. “The thing is that most people put their soap in as soon as the water starts running down. But actually the soap should be thrown in in the second wash,” Flores says. Otherwise, you may have just wasted some soap—and some quarters.

The first wash—or prewash—really just soaks the clothes in preparation for the suds that occur when the second wash kicks in. So be patient, Flores tells folks who use self-service machines, and add detergent when the second wash starts, unless your clothes are really dirty. Chances are, they don't need that first wash, and most of your soap is going down the drain.

9. SOME LAUNDROMATS DOUBLE AS AN ART GALLERY—OR A LIBRARY.

In some areas, laundromats are a get-in-get-out situation. Others try to make customers comfortable with coffee, TVs, and vending machines. But some go above and beyond—Steier cultivates her laundromats as community spaces by offering free Wi-Fi, and at her Silver Lake location, adorning the walls with local artists’ artwork. The nonprofit Laundromat Library League even stocks books in laundromats located in underserved communities across the country.

“You know when you see people on their laptops after their laundry is completed, they are comfortable at the laundromat,” says Steier. “It becomes a meeting place to not just do your laundry, but a destination to be a part of the community.”

10. CUSTOMERS SOMETIMES CALL THE POLICE.

But not everyone is just hanging out at the laundromat drinking coffee. Sohn says that his customers not infrequently break the machines by adding too much soap (more than half of a ladle, as advised against in the hand-drawn signs on the walls). When the machines break down, customers have been known to call police to complain—in fact, it happens three or four times a year. The police generally side with Sohn. “If the machine has a problem, we put an out-of-order sign,” Sohn says. “I tell that customer: Don’t come again.”

11. DISH SOAP IS THEIR SECRET WEAPON.

As you might imagine, people who do laundry all day long become an expert on stains—and most of them say you don't need anything fancy to get yours out.

“Dish soap is far and away the best stain remover. It’ll take out anything protein based (blood, coffee, food, grass, etc.)," Mehunno advises on Reddit. “For ink stains, use rubbing alcohol.”

The Cyclone Laundry and Internet Café in Baton Rouge, Louisiana, which offers a bevy of stain-busting tips online, says that alcohol stains can often be removed by blotting fabric with a mild detergent solution, or with a mixture of 1/3 cup of white vinegar and 2/3 cup of water. A mixture of boiling water and borax will take off many other stains, while shampoo is great for getting out makeup (sometimes spraying a makeup stain with hairspray will also do the trick).

12 Secrets of Roller Coaster Designers

Back in the early 20th century, engineers attempting to push the limits of roller coaster thrills subjected riders to risky upside-down turns and bloody noses. A century later, coaster designers rely on computer software, physics, and psychology to push the limits of the roughly 5000 rides in operation worldwide. To get a sense of what their job entails, Mental Floss spoke with several roller coaster specialists about everything from testing rides with water-filled dummies to how something as simple as paint can influence a coaster experience. Here’s what we learned.

1. Getting strapped in might be the most exciting part of the roller coaster ride.

Known as a “thrill engineer,” UK-based Brendan Walker consults with coaster manufacturers and parks on the psychology of riding the rails. In his experience, riders getting secured into their seats are at the peak of their excitement—even more so than during the ride itself. “The moment the lap bar is being locked down and you have that feeling of things being inescapable, that you have to suffer the effects of the ride, is the highest moment of arousal,” Walker says. “The actual ride might only achieve 80 percent of that excitement.”

2. Designers test roller coasters with water-filled dummies.

Bill Kitchen, founder of U.S. Thrill Rides, says it can take anywhere from two to five years for a coaster to go from idea to execution. Part of that process is devoted to the logistics of securing patents and permits for local site construction—the rest is extensive safety testing. “We’re subject to ASTM [American Society for Testing Materials] standards,” Kitchen says. “It covers every aspect of coasters. The rides are tested with what we call water dummies, or sometimes sandbags.”

The inanimate patrons allow designers to figure out how a coaster will react to the constant use and rider weight of a highly trafficked ride. The water dummies—which look a bit like crash test dummies, but filled with water—can be emptied or filled to simulate different weight capacities. Designers also sometimes use the kind of crash-test dummies found in the auto industry to observe any potential issues prior to actual humans climbing aboard.

3. Every foot of roller coaster track costs a lot of money.

There is absolutely nothing random about the length of a coaster’s track. In addition to designing a ride based on the topography of a park site, designers take into account exactly how much space they’ll need to terrorize you and not an inch more. When England’s Alton Towers park was preparing to build a ride named TH13TEEN for a 2010 opening, they asked Walker exactly how much of a drop was needed to scare someone in the dark. “It was a practical question,” Walker says. “For every extra foot of steelwork, it would have cost them £30,000 [roughly $40,000].”

4. Rollercoaster Tycoon brought a lot of people into the business.

The popular PC game, first released in 1999, allowed users to methodically construct their own amusement parks, including the rides. As a proving ground for aspiring engineers and designers, it worked pretty well. Jeff Pike, President of Skyline Attractions, says he’s seen several people grow passionate about the industry as a direct result of the game. “I remember when the game first got popular, I would go to trade shows and there would be kids looking to get into it using screen shots of rides they designed. The game definitely brought a lot of people into the fold.”

5. Paint makes a big difference in coaster speed.

For all of their high-tech design—the software, fabrication, and precise measures of energy—a good coaster ride can often come down to whether it’s got too much paint on it. “The one thing that will slow down a steel coaster is a build-up of paint on the track rails,” Pike says. “It softens where the wheel is rolling and hitting the track, which increases the drag.” A good, worn-in track will have gray or silver streaks where the wheel has worn down the paint, making it move more quickly.

6. A roller coaster’s skyline is key.

Brian Morrow, former Corporate Vice President for Theme Park Experience at SeaWorld Parks and Entertainment, says that the looming curvature of coasters spotted as guests drive toward and enter the park is very purposeful. “It’s like a movie trailer in that we want you to see some iconic coaster elements, but not the whole thing,” he says. “You approach it with anticipation.”

7. Some coasters arrive as giant model kits.

Whether a coaster’s theme or design comes first is largely left up to the end user—the amusement park. But for some rides, manufacturers are able to offer pre-fabricated constructions that designers can treat like the world’s biggest Erector Set. “Sometimes I work on rides that have already been built,” Walker says. “They’re produced by a company and presented almost like a kit with parts, like a model train set. There’s a curve here, a straight bit here, and you can pick your own layout depending on the lay of the land.”

8. Wooden roller coasters are weather-sensitive.

If you’ve ever been on a wooden coaster that seems a little shaky from one trip to the next, check the forecast: It might be because of the weather. Pike says that humidity and other factors can shrink the wood, affecting how bolts fit and leading to a slightly shakier experience. “The structure itself can flex back and forth,” he says. It’s still perfectly safe—it just takes more maintenance to make sure the wood and fasteners are in proper operating condition. A well-cared-for wooden coaster, Pike says, can usually outlast a steel model.

9. The time of day can affect the coaster experience.

“A coaster running in the morning could run slower when cooler,” Morrow says. “The wheels are not as warm, the bearings are warming up. That could be different by 2 p.m., with a slicked-up wheel chassis.” Coasters experiencing their first-ever test runs can also be slightly unpredictable, according to Pike. "Those first trial runs [during the testing phase] can be slow because everything is just so tight," he says. "A lot of coasters don't even make it around the track. It's not a failure. It's just super-slow."

10. Roller coaster designs can come from unusual places—like Jay Leno’s chin.

The twisting, undulating tracks of coasters can often be the result of necessity: Pike says that trees, underground piping, and available real estate all inform designers when it comes to placing a ride in a specific park. But when they have more freedom, coasters can sometimes take on the distinctive shape of whatever happens to be around the designers at the time of conception. “We had a giant piece of land in Holland that just had no constraints, and we were sitting around talking," Pike says. “And we started talking about Jay Leno’s chin.” The ride was a “loose” representation of the comedian's jaw, but “it is there.”

11. Roller coaster riders double as performers.

For Walker, the best advertising for a coaster is having spectators watch riders de-board after an exhilarating experience. “It’s all about that emotion,” he says. “A spectator basically asks, ‘What’s making them so aroused? What’s giving them such pleasure?’ The line for the ride is the audience. Imagining yourself on the structure becomes a very powerful thing."

12. The future of coasters is vertical.

Biggest, fastest, longest—coasters are running out of superlatives. Because rides can only be designed with so many drips, rolls, or G forces, some companies are looking to the sky for their next big idea. Kitchen has been overseeing design of the Polercoaster for years: It’s a sprawling, skyscraper-esque ride that uses electromagnetic propulsion to carry riders upwards instead of across horizontal tracks. “We want to put it in places where land is very expensive, like the Vegas strip,” he says. “You can only do that if it takes up a lot less space.” The project is set to exceed the 456 feet of the current tallest ride, Kingda Ka at Six Flags in New Jersey. “It’ll be the world’s tallest—and hopefully the most fun.”

This list first ran in 2017.

Here's Why You Should Always Tip Your Delivery Driver With Cash

In our microchip- and app-happy society, we’ve all but abandoned paying for things in cold, hard cash. And while that’s almost definitely more efficient for you, it could be costing your delivery driver their tip, Lifehacker reports.

Some food delivery services guarantee a minimum payment for their drivers, which seems like a good thing on the surface. Basically, the company will pay the driver the agreed-upon base payment, even if it’s a slow shift and they don’t actually reach that amount in delivery charges. But it also means that everything they earn, including tip, is going toward that base payment. In other words, your tip is saving the company from having to pay more of the base payment.

The best way to ensure that your tip goes into your driver’s pocket is to give them a tip that they can literally put in their pocket—namely, cash. If you don’t have cash around or like to keep your finances digital for credit card rewards or tracking purposes, you should choose a delivery service that promises to pay their employees the full amount of whatever they earn, including tip.

Take a look at Lifehacker’s handy breakdown below to find out which delivery services you can trust with your tips, and read the policy details for each service here.

Keep in mind that this is only for companies whose whole business is based on being the go-between for you and your favorite restaurant. If you’re ordering directly from a restaurant, make sure to ask about its own delivery rules, or just tip in cash to be safe.
