Is AUTHOR wrong in the post ? POST : So a little information, my sister (who is an adult) only likes food when it’s plain. She’s a very picky eater, and will only eat chicken nuggets and plain cheese pizza at restaurants. I’ve always thought it’s kind of childish that she doesn’t eat anything adventurous but I guess she likes what she likes. So last night I was at dinner at a nice restaurant for my aunts birthday, and the menu had a lot of exotic items on it and nothing plain enough to satisfy my sisters palate. She started complaining loudly to the rest of my family about the lack of other options, and even went as far as to single some people out and ask if they could ask the server for more plain options. She is fully grown, and should be capable of doing this herself,  But that’s besides the point. Onto the AITA. She keeps complaining and saying we should leave and go to a different restaurant, and I snapped and said “Maybe try something not drenched in cheese or deep fried, who knows you might like it.” She started yelling at me, and the rest of dinner was awkward for the rest of the family. My father told me I was out of line but I think everyone was thinking the same as me. So AITA?
