Who remembers shopping before barcodes and paying by plastic became the norm in the supermarket? How on earth did we manage when supermarket staff had to use price guns to put price labels on tins, weigh things out and manually enter each item at the till? Then there was all that sodding about writing cheques and having the checkout assistant write down the number on the cheque guarantee card or write out credit card slips before putting them in the machine with the card to have the embossed card details imprinted on the slip. It makes you wonder how supermarkets ever managed to make enough profit to grow as big as they have, doesn't it? Thank goodness they've been able to shed all those jobs and reduce our shopping bills eh?
