I hate when I am on my break at work purposely sitting alone in a corner and a customer deliberately sits either at the table next to me or in front of me and just stares the whole time and if they don't like something they feel the need to tell me. I straight up look at them like they're stupid and say I'm on my break please give me my time. 😡
