new town, old face

I used to live in Margate, kent. I moved to mid wales with my partner at the end of 2016. I left my job of ten years at a well known opticians. Shortly before I left there I dealt with a customer who had moved to Wales (we were currently in the throes of organising our move to wales). She needed her new specs forwarding to her new address. When she gave me the address, it was coincidentally the town in which I had just been for a job interview. In Wales. This was a little coincidental, as its not a large, well known town. I told my partner and forgot all about it. I got the job, on a temporary basis, and work between one and three days a week, between two different practices, in towns five minutes apart. Today, a customer came for a test. I instantly recognised her. Then she spoke, and I recognised her voice. Then I saw her name, and it was the same lady who I had dealt with before I left my old job over 300 miles away! She came to the one of the two stores that I work in, (not in the town she lives where there is also a branch), on the one day out of a possible six that I am working here. Of all the places I could have moved, and of all the places I could've got a job!
