I normally tip extremely well, especially when it comes to breakfasts. If I tipped based on the bill, it wouldn't be much of anything normally.

All I ask is friendly service, and keep my coffee cup full. If the service is really good, I'll leave 50% of the bill for breakfast, which would amount to what a normal tip would be for a regular meal. The waitress/waiter is working just as hard, no need to give a lousy tip.
