Uber and Lyft drivers reveal the things you should never do while taking a ride (LYFT, UBER)

Uber and Lyft have taken the world by storm.
Business Insider has spoken to dozens of drivers to learn more about what it's like to work for the ride-hailing apps.
There are a handful of complaints that are nearly universal among drivers.

Millions of drivers shuttle passengers to their destinations all around the globe on behalf of Uber and Lyft.

Those drivers meet all sorts of passengers, good and bad. And on the whole, their experiences have been overwhelmingly positive, dozens of drivers have told Business Insider.

But, as with any public-facing job, there will be some bad apples.

We asked drivers to tell us their biggest pet peeves, which could help your own rider rating by avoiding. Here's what they said (last names have been removed to protect privacy):

Don't eat — or at least ask first

The number one complaint among every driver was on the subject of odors. While you may not mind the smell of fried chicken, the lingering smell could end up causing a future rider to leave a less-than-stellar rating for the driver.

"Entitled riders think they can eat whatever they want in my car," Amanda, a driver in Las Vegas, told Business Insider. "People forget these are our personal vehicles."

Another driver, Matt from Wisconsin, said he didn't mind going through drive-thru windows for passengers if they ask, but on one condition: "I tell them, 'We can absolutely go to Taco Bell or KFC or whatever, but you have to wait to open it until I drop you off.'"

Other smells…

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.

Don't ignore your driver

Many passengers want to ride in silence, and probably many of the drivers, too. Still, drivers told Business Insider that contact with riders is one of the few human interactions they might have in a shift, given that they have no boss or office.

"I love to drive, but sometimes when I pick up a customer they don't say hello and just get in and start giving orders," Dorothy, a driver in the New York City suburbs, said.
