I loved C & As, used to get some nice wool coats there, and also Richards Shops. Actually I confess I still have a red wool smart knitted jacket C & A Sixth Sense, which I keep for Christmassy do's. It has lasted so well, wish I'd bought more. I always seek them out when in Europe.
I also remember Mac Fisheries at Lewisham South London, they seemed to sell a variety of groceries, not just fish. I also remember buying my first pair of shoes with my own wages in 1967, from Lily & Skinner for 69 & 11.
I worked as a Saturday girl at British Home Stores - they then sold meat pies and other groceries. I was on the hat counter along one side of the building. I was told that if I needed to open the sliding cupboards under the counter to find further supplies, I must always first poke around with the long wooden stick, to avoid possibly getting bitten by a rat!!!
