I work part time in a supermarket and one day a guy went through the self-scan (which I work on). He had been through twice already and each time deliberately messed up his shopping so I would have to go across to him.
He was nice enough and made conversation by asking me how I was and I had said I would be better when I finished work. He asked what time I finished and without thinking I told him 9pm. I thought nothing of it and finished at 9 and headed to my car - staff have to park at the bottom of the car park past the recycling containers - as I walked past them the guy I had served earlier popped out!
I was really uneasy and carried on walking as he tried to talk to me, I can't recall what he was saying but he kept saying my name and that scared me. I just wanted to get to my car and he followed me all the way until I opened my car door. He stood in the way so I couldn't close it, so I asked him to move. He asked me if I was local, which was a weird question. I didn't answer, but instead pulled my door and luckily he moved. As I started up my car he tapped the window and smiled at me. It was so creepy!
I drove out of the car park and pulled up by the petrol station and called my mum. He'd really frightened me.
The next day at work he came through self-scan again and tried to get my attention but I told my work mate and he served. The creep then came over to talk to me and because I was working I had to reply to him even though I kept it to one word answers and I pretended to help other customers until he left.
I finished work early so I managed to avoid him that night. The next day he did the same and the lady I was working with had innocently told him I was 18 after he had made conversation saying I looked too young to sell alcohol. I finished work at 10 again that night and a guy I work with did too so he walked me to my car. Nothing happened until I drove off and saw the creepy guy sitting in his car seemingly waiting for me.
After that I decided to tell my manager and she has security watch him and move him on from my till twice. They eventually asked him to not come to my service point and I haven't see him since.
