I'm celiac and happy to have been able to eat a Breton crepe. I didn't get sick. It's nice to have a server who understands. However, it's not the smile that makes his cheeks ache. We had booked without asking, and they seated us outside. So that evening, we were treated to a festival of alcoholics and homeless people, with the added bonus of bad smells. I thought I was going to throw up.
Especially since if they had asked me, I would have eaten inside where it was warm.
