Tipping can be a surprisingly hot topic for some people. I've heard some say they feel insulted that a server expects a tip, but I've always been a good tipper because of past waitressing experiences. I've felt their pain. Of course there are instances where a bigger or smaller tip may be appropriate, but I've definitely never left a tip that would make the server's night worse. What about you: Are you hard to impress when dining or do you have a pretty standard tipping etiquette?
