I have a very manly and very (w)itchy lady who works at my Petco. She really pissed me off last time she got me some mice and rats, so I asked her if I did something or if she acts like an a$$hole to everyone. She said "I'm just a (w)itch". "oh, ok". Like you said, I'm very patient and polite, but this one makes it a point to show how angry and uncaring she is at all times. There are 2 really nice and helpful ladies who work there. I always look forward to seeing one of them if I run out of rats.
