I also worked there on the cakes counter in the late 1960s. I was always late and kept getting told off, so didn't stay there long.My Mother worked on the counters there around 60’s/70’s. The store was somewhere near the underpass to Lewis’s main entrance then as I remember.
And I think that mindset still persists with different names!As I mentioned some years ago, I sometimes had to go with a delivery van to Roman Road, in Streetly, where a very small basket would be delivered, containing a quarter pound of tomatoes, a cos lettuce, a cucumber and a small punnet of strawberries. The obvious point, was to be seen having the BARROWS van outside.
