The Co Op in Gillingham High Street also had the overhead runway for the money to be transferred to the cashires' in a central, elevated, glass sided "shed". In the early 30's, I used to go shopping with my mum every Tuesday & Friday & was fascinated by the system. We shopped a lot at Co Op's ( even had our hair cut there), for the divi paid for our Christmas dinner( medium or large chicken). I still remember our number 1509.
