While I was a young child in 1940s Britain, there were far more small shops than there are today. There were some chain stores, but many were owned or run as family businesses.
The individuals serving in the shops tended to have to manage the stock as well as serve. So they were kept busy, often out at the back of the shop. In order to know that they had a customer, they needed to be alerted in some way.
One type of alert was to let a shopkeeper know that a customer had entered the shop. This was done with a bell above the shop door which was tripped to sound as the door opened.
These early bells were manual ones, not electric ones, and they made a characteristic 'ting' sound as the clapper hit the bell casing. The 'ting' couldn't always have been easy for the shopkeeper to hear from out at the back. Later bells were electric, rang for longer and were louder.
Once inside the shop a customer could call the attention of the shopkeeper by ringing a bell screwed on to the shop counter. This bell, too, was manual. The knob at the top had to be pressed smartly down to drive the clanger against the bell casing. It was not an electric press button switch. It had the advantage over the door bell in that a customers could press it more than once if the shopkeeper did not seem to have heard the first time.
While I was still too young for school in the early 1940s, my mother had to take me with her when she went out shopping. She said that some shops and much of the shopping process had hardly changed since her early 1900s shopping experiences.
