I waved at the waiter to ask him to come back to my table .  I told him politely that the food I was brought was not what I had ordered , and asked to have it remade so that it would not make me sick .  The waiter said he was sorry , and asked the chef to make my dish again without the food I was allergic to . Question: Who made the mistake?
