A tip is earned. A tip can also be lost.

In restraunts I tip 15-20% for very good service. If good service then just hte standard 15%. If the service gets worse the % goes down. if it is terrible I would not tip anything, which has only happened maybe once.

If the service was so bad I didn't leave a tip I simply wouldn't go back again. What gets me is when the place imposses a 20% tip on parties of 8 or more. I guess it is no longer a tip but a mandatory price increase.

The tip to the waitress never includes the price of the alcohol served with a meal.
