Fortunately, a week later, they came back and informed me that they had decided to eliminate the bread crumbs from the potatoes, making the main course entirely gluten-free. The salad was served with a cracker on top, but they made sure mine never touched the cracker. When I checked in at the front desk at the beginning of prom, I was handed an index card with my name and the words "gluten-free" written on it. I gave this card to the server, who then made sure that everything was gluten-free, as seating was random. I did make sure to double check with the server to make sure that everything I was eating was gluten-free, because no one wants to be sick on prom night!
