As an American living in Australia, I really do miss tipping. I think that on average the restaurant service here is a lot lower. At most restaurants at the medium level (e.g. $25 hamburgers) you pay in advance, and then a waiter will bring the food to you when its ready. Do you need more water? Get it yourself... Ketchup, you have to ask but it won't be offered. The waiters don't care because they are making good money anyway. The only place you get American style service is at the very high end places.
