I wouldn't let the experience with the rude waiter stop me from enjoying dinners at Artista (for all you know he's probably not around anymore). I think you are over-exaggerating...I have traveled to many different places and wouldn't feel ""humiliated"" for not knowing the ""etiquette"" of the hospitality industry in that country...I would take it as a learning experience for the future and laugh it off. Period.
