My favorite is the so-called "tipping guide" that some places have taken to printing at the bottom of your tab. You know the ones....at the bottom of your bill or credit card receipt is a little note letting you know what 15% of your bill is, and 20% and so on....

While this seems to go hand-in-hand with the restaurants that have a little card on the table (real classy joints!) regarding tipping for our foreign tourist friends (who are, as mentioned earlier in this thread, not used to our tipping culture), the things that REALLY bother me about these tipping guides are:

a) Most people are not idiots and can do the math themselves (I know...there are exceptions)

b) The calculations seem to start at 15% and go up only. I guess if you got crappy service you have to figure out your substandard tip yourself!

and my absolute favorite (drumrole please...)

c) They always seem to figure the amount based on the total tab AFTER taxes, which they know is NOT the custom. In places like NYC this can make a big difference.
