Yep. already put my thoughts about tips on a previous post of yours.
So important to give a good tip. However.... I have no problem leaving a bad tip for bad service. and you know the difference between a mistake and a horrible waiter.
it's rare. but on the occassions that I do get one - I'm definitely not going to contribute to any false notions that they stay in that line of work. going out to eat should be a fun experience. and its expensive. i respect waiters (hubby used to be one and is now a chef) but they need to respect their customers too.
Well it's true that everyone has a bad day now and then but for the most part you're right they should be able to provide you a good experience.
