I was on the Valor last week and we took the galley tour given by the Matre D. The question was asked what do they get paid and do they get to keep their tips. This is what he said. The wait staff is quaranteed a certain salery based on their tips. If at any time they do not make that amount Carnival will make up the differance. Otherwise Carnival does NOT pay them. I assume Carnival gives them their room and board and does not deduct this from their salery.
