I had thought the same, but a year a later that waiter was working at a different restaurant, I like. Needless say I have very distinctive hair. whether or not they remember me because my hair or not leaving tipping I don't know.

Still was interesting they remembered me a year later from a restaurant I only went to once.

A waiter sees hundreds of people every single night. Unless you were particularly rude or did something memorable, I don't think they'd remember. People always believe people are paying more attention to them than they really are.

Hell you probably weren't the only person not tipping that same night.
