And coming from a culture that does not routinely tip this confuses me. I "get" the tipping while I'm sitting in the restaurant and try to be a good tourist and do it right, however, that tip is based on how attentive/good the service is while I'm dining. In the in room dining situation, the meal is dropped off and that is the end of the server. Why is the expectation that the percentage is going to be as high?
