The restaurantwent public with the small tip earlier this week, by posting the receipt it claimed was McCoy's on its Facebook page.
"I just thought it was pretty callous and insensitive," PYT owner Tommy Up told NBC10 in Philadelphia. "Twenty cents isn't an industry standard."
According to an article NBC10 posted, the waiter who claims he served McCoy and his friends said things didn’t go well, including making a mistake on their appetizer.
The waiter also told NBC10 McCoy and his party acted rude toward him.
PYT has received a mixed reaction after posting the receipt on its Facebook page. Some people have commented that it was unprofessional on their part, while others sympathize with the server.
