As everyone knows, tips constitute the bulk of a waiter's or waitress's income. But they are also optional, at least in theory. Does it really seem like a good idea to make someone's salary so susceptible to customers' whims on a given day - or whether any customers happen to show up at all?
Just being aware of what you are about to do greatly diminishes the tendency to do what you don't want to. You will pull your hand back from that pizza slice, tell the waitress that you are passing on dessert, put on your gym shoes instead of going under the comforter, and take several deep breaths instead of screaming at your daughter.
Coming home, we stopped for a bite to eat and ran into a confused waitress.
