Doesn't even have to be a fancy place; I saw a similar story at my favorite neighborhood dive, a Mexican/Salvadorean place with great pupusas, no atmosphere and nothing on the menu over $14. It was a really busy night and they were clearly under-staffed (I think it was the Sunday of a 3-day weekend so they got weekend business but were expecting a quiet Sunday night) and the waiters were really busy. The woman at the next table sent pretty much everything back (including her boyfriend's 3/4-eaten steak), did the whole DYKWIA thing, complained about everything. The owner was at her table constantly and nothing was good enough for her, not even the free meal. When they stormed out, she stole the bottle of hot sauce off the table (a bottle of Tao Patio which usually retails for about $0.89 around here).
