Bonus Restaurant Horror Story: Beware the Sangria

Still cringing over our last batch of Restaurant Horror Stories? Well, to close out Service Week, we've got another doozy for you, sent in from a reader:

A man at an Italian eatery in Philadelphia ordered a pitcher of sangria and drank it by himself directly from the pitcher. He then went to the lobby, pulled down his pants and... well, let's just say it wasn't pretty. The security guard told him he had to leave, so he went out to the parking lot. He didn't pick up his pants until police arrived.
