I have been friends with a woman for a while now, but recently, while in a cafe, she was awful to the wait staff after the service was a little slow (it was busy) talking to them like they were sub-human, and being rude and demanding. It was embarrassing! Ever since then I've thought less of her, and now not so sure I want to be close friends with someone who can be so unkind to others. She's always been nice to me, though.
AIBU to think less of her because of this one event? She wasn't having a bad day to my knowledge, and was perfectly pleasant to me both before and after talking to the waitress - as if nothing were wrong.
If IANBU, is there anything else that makes you think less of someone like this?
