Kendall Jenner reportedly threw money in a waitress' face after leaving a restaurant without paying.

The 18-year-old reality star was denied alcohol service at Mercer Kitchen while dining with Alec Baldwin's 17-year-old daughter, Hailey Baldwin, last week. A witness told Page Six Jenner was upset "the staff wouldn't serve her because she's underage," and decided to dine and dash.
"Kendall got up and left and didn't pay for all the food," the source revealed. "About $60 worth, and without a tip."
Jenner and Baldwin are said to have "started laughing" when their server, Blaine Morris of MTV's Skins, ran outside and asked them to pay their bill.
"Kendall took a couple of $20 bills out of her wallet, threw them at the server and walked away, not even counting if it was enough or if it included a tip," the source detailed.
Morris tweeted shortly after the incident, "That horrible moment when you chase a kardashian down the street because she forgot to pay her bill to be thrown money in your face."
"They thought everything was paid for. Kendall was polite and asked, 'Does this cover it?' They didn't run," a rep for Baldwin told the publication.
