I knew a dweeb who would go to “The Calico Cat” in Portland, and while others lined the seats at the ‘tip rail’ this dweeb would move from side to side, behind those other patrons, standing behind the guy who put a dollar or two on the tip rail… waiting for the wide spread meant to be the paying customer’s treat.

Then, upon conclusion there, this dweeb would move on to the next tipping customer, and stand behind him and steal some of his thunder as well.
