I know that it has been said that tips are not customary in FP I found this very confusing while I was there. We just got back to the states today and this was one thing that I thought that I should give people the heads up about. First when we paid at the hotel with a room charge there was always a gratuities space on the tab. I felt very obligated to put something in this space and it was always appreciated if I did. Also the restraurants that we went to also had this line (Alfredos twice and Aitos once). I know that you as a restaurant owner can set up the tab to not have this space (in the computer) so I also felt obligated to add something to this line. Granted I never tipped 20% as I would here in the states as the food was already so expensive but we tried at least to shoot for 10% plus there is the 2% service charge on the checks as well. However when we paid at the hotel straight with a credit card, not room charge, there was no line for gratuities. I just found it very confusing as did a few other guests that we consulted. Another note is that there is a big sign in stick-on letters on the Alfredo's transport van that says "rides are free but tips are appreciated". So to say that tips are completly uncustomary, unexpected and even insulting, I think may be an outdated statement.
I will write alot more about the whole trip later (WHICH WAS GREAT!) but I wanted to put this one out there as it was one of the most confusing things abot the trip.
