Unforgettable Celebrity Encounters, Courtesy Of Reddit

4. Kevin Hart
One redditor worked at a bar while in college, and one night Kevin Hart came in to eat. "He wasn't really that famous at the time. I didn't know who he was, but I was curious as I had to go to the stock room to get a $1000+ bottle of champagne that he ordered in addition to pouring a bunch of really expensive top top shelf shots," the redditor shared. "His bill ended being well over $2000. The girl who had his table (who also didn't know who he was) said he was by far the most demanding and rude person she had encountered while working there and that he was extremely demeaning. He ended up leaving a $4 tip, all in crumpled up singles."
