Earlier quoted context omitted.
In many places people still haggle for most things. Even where I live (Melbourne, Australia) a very non bargaining place, some restaurant districts have bargaining cultures. If you play your cards right, you can get wine and dessert thrown in if you order the steak, site by the window before the dinner rush (makes the restaurant look full).

I'm living in Melbourne and I am unaware of this. Wine and dessert? Surely you must be joking.
I am a bit more shifty as I normally have the target place chosen before I even leave home and will try to make sure the maitre d' seeing me chatting to next door so I can play him off against them.
It is all good natured and they expect it.
