Dollar General, Thompson OH

I left about fifteen minutes ago. I was just going to let this go, but it was so beyond rude I needed to say something. When I went to make my purchase I told the cashier I would just use self checkout. I do that because I prefer to not deal with anyone. She gave me a skeptical look and followed me to the self check out. She leaned into the area and proceeded to tell me how to scan things and to separate them in bags based on if they were hot and cold. I tried to ignore her making it clear I wasn't interested in her tips. She didn't seem to care, she proceeded to try telling my eight year old how to bag the items. It was a really odd interaction. I don't know if she thought I was going to steal something. But if she thought that she could have at least watched to make sure I didn't take anything from a distance. It didn't feel like she was trying to be helpful for me. It almost felt like she was offended that I didn't let her check me out. Whatever the reason, it was not ok.
