Here in Israel it's similar, although ten percent are considered okay.
After one year here it still annoys the hell out of me. In Germany you only give a tip if you consider it appropriate. Your service costs exactly what the bill lists, not more. Especially in crappy places a 'forced' tip feels bad and wasted.
I fail to understand your answer. Maybe you've got a good point, but the current reply is too short. I fail to see what you mean.
The 'whole point' was a discussion about mandatory tips. If you don't tip here it's not rare for the service guy/girl to get quite mad and insulting. You HAVE to tip, forced by social norms and by demanding workers.
