If you have a disease that serious and sensitive then you should be working with a doctor and eating meals that you know are safe, like the kind you can make at home, not relying on redditors and service industry staff to keep you healthy. If you're that sick and looking on reddit for answers, then yeah I don't understand.

If you have a diagnosis, then I would think that you would know the details about how things get labelled as gluten-free, and how much is considered to be a harmless amount (Spoiler: it's at least two orders of magnitude more than you could get from cross contamination to wine in barrels sealed with wheat paste)

As a matter of fact, I understand gluten-related disorders pretty well. The people that decide to go against the recommendations of health professionals and go gluten-free in an attempt to self-diagnose, and the ones that make the lives of waitstaff around the world harder by not knowing what they're talking about, not so much.

If you have a diagnosis, then cool. But if you do, you should definitely know that you're 100% fine eating a spicy tuna roll from anywhere you want because your doctor should have explained that sort of thing to you. But since you don't know that, I'm assuming you don't have a diagnosis.
