What was your worst restaurant experience?

Worst restaurant, HHMMM...There were 14 couples at a car show in Waco, Texas and we decided to celebrate one of the wives b-day. We drove our cars to the local "Red Lobster" and got preferred parking, which meant one of the bus people watched our cars to keep the locals from fingerprinting them while we ate and had a good time. To make a long story short, we didn't get to eat at the same time as the food came out slooooowly. My wife at the time and I were the last to be served...I had the fried shrimp platter, and as I picked up one of the shrimp I brought at least 4 more with it. They were all connected by three strands of long black hair...I came unwound at the manager and was told we were paying for the meal. Guess what, we walked the entire bill...I have never eaten at a Red Lobster since, and I doubt if I ever will again in my lifetime.
