My(28f) friend has a cousin 'Molly' (30ishF) that she's close to. I've met her a handful of times and until this incident didn't think one way or another about her. There've been a couple of weird things prior and after asking my friend, no Molly isn't on the spectrum or have food aversions. Which leads to why I'm posting here:
A friend invited us out, and she asked if Molly could come along. While we were ordering Molly kept making a big deal with the waitress about how she didn't want 'raw' shrimp with her meal, she wanted it cooked. Molly pointed to the table next to us where one of the people had grilled shrimp and said "That's what I mean, I don't want raw shrimp. I want it cooked." The waitress was a champ and told her she'd ask if they could substitute tempura shrimp for the regular grilled shrimp. While the waitress was gone, my friend told Molly that the shrimp is cooked and not raw, it's just grilled. Molly went on a whole tangent about how it didn't look cooked to her, insisted that it was raw. Whatever, we order and try to drop it. A couple of us got regular shrimp with our meals, myself included and I got a side of tempura shrimp cause that stuff is good.
So here's where I might be the AH: When we got our food and started eating Molly made another comment about how she didn't get how we could eat 'raw' food like that and we were going to get sick. I had enough and told her that our food is cooked, and the only difference between our shrimp and hers was the breading, so I peeled off the tempura from one of my pieces, and held it and a regular grilled shrimp up to her and went "See? They look the same, the shit is already cooked you're just being willfully ignorant." Molly excused herself to the bathroom and the vibe was killed after that. We got our food to go and paid right after that, and I did apologize to the rest of my friends. My friend, and another of our friends have been on my case the past day and a half over this and keep telling me I need to apologize to Molly. I don't think apologizing to her is warranted in this instance though- its one thing to have a hang up over a food item, but it's another to keep making comments after you've already had something explained to you. AITA?
