Things fast food places do that make you mad. Which one makes the most mistakes?

A friend and I went through the McDonald's drive thru - he ordered the Filet-o-fish...NO TARTAR SAUCE. They confirmed, "So that's no tartar sauce, just fish and cheese on the bun?" He said yes, we drove away. Imagine how angry he was when he opened his fish sandwich and it was a bun...full of ONLY tartar sauce, no fish and no cheese.
