She did actually agree to have that information shared with the other passengers and then still bought all the peanuts. I'm not saying she's faking her allergy or something, I'm trying to wrap my head around her train of thought here. You can also take a car, a train, a bus, all means of transportation where the transport company doesn't sell you peanuts. Yeah it's less convenient but shit man, it won't kill you.

Ideally she wouldn’t have to, peanut allergies are pretty well known and if we cared about increasing access for people not having peanuts for sale on planes is a pretty simple step

100% agree with this though
