I'll complain about the food if it's off, but only once did I complain to management about the waitress. That was when I'd had a long day on the road, and I pulled into a hotel for the night. The restaurant was empty, but they served me an expensive meal nonetheless. Certainly there was lots of time according to the sign on the door. I guess the waitress was kinda anxious to go home though, cause she ran the vacuum cleaner around and under my table as I was eating my dinner.
