Is AUTHOR wrong in the post ? POST : Background: I hate American cheese and I hate mustard. Absolutely hate em, I think because they're unnaturally yellow. 

Anyway, my girlfriend (whom I've lived with for over a year and 1/2) has a habit of having food delivered without asking what I would like. She'll just order for me, which is fine most of the time. But every time (okay it's only like 3 times) she's ordered me a burger it's had cheese and mustard. I end up not eating the burger and finding something else. Which is okay, but I told her each time why I wasn't eating what she ordered me. The third, and most recent burger, had mustard, cheese, and mayo (gross). I was a tiny bit upset and asked her something like "do you not think about whether I will like something before you order?" She apologized and that was that. 

But, it's been bugging me, AITA for being upset she ordered me food that will just end up in the trash?
