Dude comes to complain about a hangover after few pints of bad ale, gets an unsolicited diagnosis for an auto-immune disorder.

I know a few people who are celiac and there are much bigger giveaways than having a hangover after 3 beers (the latter of which isn’t that uncommon of problem for people who don’t drink often).

I’m pretty sure the average daily gluten intake of this person is much higher than that from 3 beers..
