There’s a local coffee shop I often attend to do homework on weekends. I’m often there for several hours at a time. There’s a man who comes in there and is usually there most of the day. He sits down, orders a coffee, and just stares at the wall. I think he might be high but I don’t know for sure. He bounces his legs a lot and sometimes he stares at me and then looks away when I see him. I see him doing the same to other young women.

He hasn’t said or done anything disruptive, doesn’t seem to want to hurt anyone, he just sits there with his coffee and stares. I have nothing to go on but the heeby jeebies. Would I be the asshole if I mentioned it to a manager? Am I overreacting? Would the coffee shop even be able to do anything? This can’t be just me, other people have to notice too...
