30724........I chanted it all the way from home to the Co-op for fear of forgetting it......
When I'm old, dippy and forgetful I'll still be saying....30724.. :-)
393 upto about 1960 then it went to 6 figures, still ending in 393 but can't remember the first bit. Didn't have to chant it though as the Co-op was about 30 yards from our house at the time.
Mother's number was 568, easy. When me and my school friend were old enough, 16 I think, we got our own Co-op numbers and used them to cream off the divi when we were sent to buy stuff at the Co-op.
I worked in the co op many years ago. I remember filling the slips in the passbook (and adding up the page). I also worked in the office upstairs for a time. All those slips turned up there, and we had to put them in numerical order, and stick them on a sheet, so that the co op would have a record of the customers transactions. There were about 25 girls working in this office. This was in the 1950's
