Glad you found it interesting. I worked at the branch at the Holly Bush, Quinton when I was at school, during one summer holiday. Those bikes were trecherous and I do rememebr selling a jar of fish paste to a customer. I was supposed to be shelf stacking but as I turned I came more or less face to face with the lady and expecting to be served, so i did. Althought I dont think i was supposed to but it would have been rude I thought not to.
I only did it for a while as I realised although the money was useful I was wasting valuable time that could be spent train spotting!! I remember the bloue and cream bedford CA vans and the shop did have a destinctive smell that only grocers shops do have.
