Lewis's (and other firms') ice cream
Sylvia's note on the ice cream machines in Lewis's brings back memories -but mine were not so fond.
From when I was a real nipper before the war, I can remember only two brands - Midland Counties, whose tubs had a blue-and-white diamond checker pattern round the cardboard sides, and Wall's, who had a depot in Nineveh Road, right next to the bridge over Hockley Brook, just round the corner from my three surviving grandparents. A small army of 'Stop me and buy one' men went out from there every day on their tricycles. With rationing and so on, I think ice cream went off the menu from some time in mid to late 1940.
The next I remember about ice cream was at a department store in Leicester in early 1945, (I think it was another branch of Lewis's, but I am not sure now), when a substance looking like off-white non-drip emulsion paint was being put into cornets that were probably years old. As I remember, the taste was mainly of powdered milk, saccharin and cornflour, and it left behind an unfamiliar feeling on the tongue, reminiscent of diluted cod liver oil. Yuk.
Not long after that, a similar substance was sold at the Birmingham Lewis's, as I remember in the base lobby in Bull Street close to Grey's. Shortly after came the d-i-y machines where I think you turned a small lever rather than pressed a button, and the mixture oozed into your empty cornet. I believe you paid a cashier before leaving, rather than putting cash into the machines at that time.
I would guess now that it was not until 1946 or 47 that the battery of slot machines Sylvia mentions were working. By that time, ice cream was quite nice, I remember.
