| I tend to tip pretty generously if I feel I actually got good service.  Otherwise I'll just go with a flat 10% "Wow you did your job!" tip that I feel I do more out of obligation than anything else.  Rarely do I actually get bad enough service that I won't tip at all, but it's happened from time to time.  I personally think it's an annoying custom, because it's gotten to the point where a customer is a jackass if they don't tip for even sub-mediocre service.  However, it's not as bad in the U.S as it is in Europe.  In all my experiences over there, they expect a tip for every damn little thing that goes on.  It's like you're walking down a sidewalk, and someone coming the opposite direction doesn't bump into you.  Next thing you know, he's holding his hand out waiting for a few pounds. |
