I work in a cafe/shop. Today at work a man came in, was chatting away, got his order etc. I went to the bank with takings and he appeared chatting away. Asked me what time I finished, what days I worked, if I was married. I just kept it brief, didn't get into detail about my shifts. Anyway, when i was closing up he appeared again, standing really close, I was out the back in secluded area, no one around putting the rubbish out,!-and he pressed up against me to get passed but it was inappropriate closeness if you know what I mean.I felt really vulnerable. He said he was working tomorrow as am I and said 'same time same place'.
Im freaking out about him. Aibu to boot him in the balls and tell him to back the fuck off?
