i kinda fill morally obligated to tip the waitress if the service was good, but it makes me so mad that for that reason and that reason only, i rarely eat in restaurants any more. it is not the matter of money, but principal. if the food and drinks are say 1000RD, they will charge for the service 100RD, whether the service was good or bad, and whether the food was good or bad, then on top of that they expect you to tip! shouldn't it be my choice whether i want to tip or not?
