My parents bought a large shop with two flats above, in Preston Village on the corner of Lauriston Road and London Road in 1967.
Old fashioned counters
The shop was really old fashioned with long wooden counters running the length of the shop each side and a delicatessen counter at the far end for bacon, cheese, ham etc plus a coffee grinding machine. The goods were displayed on shelves behind the counters so the staff had to walk up and down fetching items for the customers.
There was also a small square office with a glass window with speaking panel next to the deli counter where some people came to pay for their groceries on a monthly account basis. Once we had settled in, my father modernised the shop to make it self-service apart from the greengrocery, deli and off licence sections.
