I had a really unsettling incident in the supermarket last week. A complete stranger started following me around, standing near me, watching me. I'd taken my mother shopping so found her and explained to her what I thought was happening. He quickly appeared near us. Whatever I went to look at, he turned up by us. We would move several aisles straight away and he still appeared. He'd stand and watch me, or try to get to whatever I was looking at. At one point I said sorry and moved away hoping it would de-escalate the situation. It happened about 10 times during my visit. He felt malevolent and cross with me. My mum said afterwards she was trying to block me from him with her trolley.
In the end we just decided to leave and check out. I saw him leave through the self checkout while I was at a staffed till. I didn't see him in the car park or I would have gone straight back in to the shop.
I got really cross with myself on the way home that I hadn't asked someone who worked at the supermarket for help. I felt so silly at the time and it just felt too surreal to go up to a staff member and say I was being followed. But on the drive home I realised I needed to do something. I rang and talked to the supermarket and explained what had just happened. I also wrote down everything I could remember about the incident and emailed it to the manager.
I explained that I was really worried about him doing it to someone else and I couldn't believe that this was an isolated incident. That I recognised this is not the shops fault and that I didn't talk to anyone at the time. He sent a pleasant reply saying that he would have it investigated urgently and to let them know if there is anything else they can do to support me.
I guess I'm wondering if there is anything else I should do? Would it be appropriate to reply and ask to be updated on their findings, or if it was an isolated incident? I have been assuming that they won't really be able to tell me what they find out so haven't wanted to put them in the position of having to tell me so.
