Uber and Lyft drivers reveal the things you should never do while taking a ride

It doesn't stop at food. Other smells can have an even more drastic effect on a driver's ability to keep working. The number one culprit is marijuana.

"Young people get in my car all the time reeking of marijuana," Wallace, a driver in Connecticut, told Business Insider. "I don't mind personally — as long as they aren't smoking in the car — but if another passenger so much as complains about the car smelling like weed, it can get me deactivated from the app."

Stan, a driver in the Cleveland, Ohio area, said he uses a Febreze spray after any rider "with extreme pet or body odor when they exit the vehicle."

"I've been pretty lucky with passengers, but when they get in right after smoking a cigarette it can linger in my car which can then lead to a bad review," Gabriella, a driver in Boulder, said.

Uber (and Lyft) drivers are, more often than not, using their own personal vehicle to provide rides. They consistently said they wished riders would also treat them as such.

"Far too many people slam my very light doors," Joe, a driver in Phoenix, said.

On minivans with automatic doors, things get even more complicated.

"I finally just put up signs inside and out telling people to not touch anything," Menard, a driver in Miami, said. "Just let me open and close the door. It's much easier."

Even Uber's CEO agrees. "Don't slam the door," he said in a recent interview.

Lyft and Uber both prohibit passengers under 18 without a parent or guardian, but that doesn't stop many parents from ordering rides for their kids, or from teenagers requesting rides on their own. It can land drivers in serious trouble.

"No one under 18 should be getting rides unsupervised," Zachariah, a driver in Los Angeles, said. "I cancel those but feel really bad about it."

"My main issue is people that use me to collect their young kids from work or doctor's appointments and don't have a car seat," Zachariah continued. "I tell them I can't drive their 2-year-old and they get pissed and say it's fine, but it's not and puts me at serious risk of a lawsuit so I cancel the ride and drive away."

This was the number one complaint among female drivers we spoke to.

"In only two months doing this I've dealt with everything from having my breast fondled to my life threatened," Amanda, a driver in Dallas, Texas, said.

Other women said they only drive during daylight hours to avoid problematic encounters.

"I get rude and harassing comments from men in the day, so I don't even want to know what it would be like at night when people are drinking," Jenny, a teacher who drives in northern New Jersey during breaks in the school year, said.

After five minutes, Uber will charge a no-show passenger, but drivers aren't paid during that interim time.

"My biggest complaint is waiting on passengers beyond the required wait time," Jeff, a driver in Colorado, said. "You hit the button to request the ride. What are you doing?"
