Partygoers Mocked By Catering Staff "Whenever people are forced to serve others, resentment and derision are inevitable," said Dr. Henry Janssen, a University of Georgia anthropologist. "This tradition dates back to Ancient Greece, where servants at grand Athenian feasts would sneak into the kitchen to put on short plays lampooning the foibles of their wealthy, gluttonous guests. As long as there are people who stuff their faces with mini-meatballs while wearing bad ties, there will be servers there to make fun of them."
