I am not sure about tipping when you are on the dining plan. Do you just leave a cash tip. Since you are not using a credit card for your meal. I wasn't sure what they were trying to say on another thread. I thought they were saying that you have to put it on a card. We are trying to deal with cash (no bills when we get home). I would think they can't make you pay with a card and do they tell you how much you have to leave them we are a party of 3.
