I am not only a vegetarian, but i have a pork allergy. I get really fucking sick for days with pork contamination, so I'm that asshole that questions waiters minutely. "Is there any lard in this? Did it touch bacon or bacon bits?"

I collect safe cuisines like celiacs collect gluten free food sources for pretty much the same reason. it's extra important when traveling as that whole two days in the bathroom thing puts a real cramp on trips.

I am not celiac, but I do have a lot of sympathy for my homies with celiac as it's a lot of the same sort of hassle getting safe food, I think. I live in an area where I don't have to think about it a lot unless I'm traveling or eating somewhere new, but when I go back east, it's still a big issue finding kosher and halal food sources as at least that way I know no one's cross contaminated me with pork. (It's not like I can properly digest other meat, but it's nowhere near as dire.)
