I've been cashier since I was 12, so I know how to treat people. But I just got back from the convenience store. I was having trouble using the penpad. The cashier said that I had to use my finger instead. So I just kept trying. As I left someone behind me said, "now you know." If they even paid any attention they would have noticed me use my finger first then the pen. Why do people seem to want to be rude to others for no reason than to be. Maybe, I misunderstood her. But I had the same thing happen in another convience store when I asked where the restroom is. I think I'm more sensitive because of past experiences. Sounds contradictory. But I'm 39. I think I'm prone to bad luck with people. I do really well as a cashier. But outside that I'm like constantly being misjudged.
