Etiquette is fine by me if it's only to react to cvommon situations in foreign countries. I'm in general agreement with the "proper" reactions mentioned above, although I don't believe we Indians should be on the opposite side, i.e. the one initiating the compliment on the other person's suit. Such people always leave me wondering about the sincerity of their compliment. American etiquette is full of such soft lies and quick deceits that I worry when an etiquette trainer is valued more highly than a Standard III English teacher in today's society.
