You sound like a good worker. They could just be nasty people and they probably sense something is different about you so they are picking on you. I would say it sounds like a bad store. From what I understand, autistic people are more vulnerable to abuse and an easier target for workplace bullying. This can happen to NTs too but it's more common in people on the spectrum. It even astounds me how immature adults can be. I thought we were all done with this after we get out of high school. Just remember, some people take longer to grow up.
