Why don't they call "TIP" simply a "Service fee" and add it to the price? Then I can give really "TIPS" as an extra which must not be in the 15-20% range. Thats how they do it all over Europe.
Question: how does a waiter know that you pre-paid the tip? Do they get an info about evrybody at their tables? My understanding is that I have always the choice of automatic tip and envelop tip.
One more: when I tip on earlier occaisons (day one, in between), will the waiter/server keep this money for him/herself?
