I can remember going in to the Stakeford COOP as a boy with my Grandmother, no self service in those days just about everything sold was loose and was put up to the customers needs, sugar was weighed and put in to blue paper bags, butter was in a huge lump and the customers requirement was cut off and shaped using wooden spatula kind of tools then wrapped, same with cheese cut with a cheese wire and wrapped, bacon was sliced to the customers preferred thickness. The counter assistant who served you did not take your money she sent you bill whizzing along one of those zip wires to the cash office and they sent you change and you dividend receipt whizzing back to the counter.
I can still remember our check number , what a job it must have been for the cashiers in those days working out all the yearly dividend payments using nowt more than a pencil and paper.
