Quite a few years ago, in now-defunct downtown establishment, a few of us from work were at lunch. We were on a long lunch, but not unlimited time. About halfway thru we noticed our server was absent and inquired with another to get something or other. Just then, the service door flew open, our server and a manager burst out and a bit of a screaming match went on in the middle of the dining room. The server threw his apron at the manager and stomped out. We managed OK, but about a week later I was out with my family and we could not locate or server. The manager came out and profusely apologized, saying the "girl went on her break and never came back". My family now comments when ever restaurant service is slow that I ran another server off!
When I was a server at a small family style restaurant, we had a group of folk that would come in, eat meals and leave us religious cards that
said it was in lieu of a tip. Needless to say no one wanted to wait on them when they came in.....
