When I was a kid (born 1962) supermarkets sold mostly tinned food, bread
( brown or white were the choices) and fresh meat from a separate counter, not much else, tobacco sold at the till. No clothes, electrics, kitchen ware, bedding, toys, books magazines, newspapers.
A few bits of frozen stuff but few people had freezers. Looking back, we had nowt really.
They introduced alcohol kiosks, tiny little things, nothing like the lane after lane of alcohol you see now.
People went the the offy ( off licence) for alcohol to drink at home, but way less alcohol was consumed like that.
Most people went to the pub. The price difference between pubs and off licences wasn't that great, its huge now.
Pubs were great in the 1970s and 80s, we have really lost something and it won't be back.
Growing up all we wanted to do was get in the pub from age about 15, some pubs weren't too fussy and you kept your head down and behaved with your 3 half's of cider. Which you could afford on your pocket money.
Drugs way cheaper and easier to access for kids now.
