Also, it's annoying when they don't have that information in the restaurant. I asked at McDonald's right after I was diagnosed, and while the manager was extremely nice and sympathetic, the brochure she gave me just referred me to their website. Thanks, Ronald, that really helps when I'm standing in the restaurant right now.
Finally, celiac disease isn't contagious and asking about what's in your food doesn't make me a freak. Honestly, Panera cashier, I don't have an alien baby parasite in my guts (even though it feels that way sometimes) that's going to pop out and eat your face. I just want to know if there's any wheat or gluten in the french onion soup, sans croutons (there is. sigh.).
