I agree too. When we were there in September we noticed that some places added the 15% to the bill so we said if that's what they think is fair, who are we to argue, even though in the states we usually tip 20%. What we were told is that the servers aren't paid the same low wage structure as the servers here in the states are. We were also told that the owner gets a percentage of that service charge so therefore I have to say that if deception is the motive, they lose. If there's no service charge then we will start at 20% and go UP from there.
