Saturday Centus … Please remit payment promptly.

In 1967 I worked as  clerk in an  accounts  office; one side the buying department; accountable to the bought ledger. On the other, the marketing section reporting to the sales ledger. In the days before computers and calculators; the hand written ledgers, huge leather bound tomes, loomed on the accountant’s desk like a pair of demanding crows.

Day by day the buying department worked out ways in which money could be saved  and cunning ways in which to delay paying the bills.
The sales department was spurred on to increase sales and send out invoices;  stamped in red ink;  please remit your payment promptly.
