OP here. First submission got posted :) there is no HR to talk to as there was only me, the owner and another coworker and we all got along just fine. I do have Resting Bitch Face but I'm aware of it and consciously smile to make up for it. I also did not have a bad attitude. The worst part was that I was still training so I haven't had time to meet the requirements of the job or not. Oh well, she was a flaky boss anyway. But she said she'd give me a good reference.
