Our shopping trolley shame

“Does this scenario sound at all familiar? You go haring off to the supermarket because ‘there’s nothing to eat’. You pile your trolley satisfyingly high — after all, who goes to the supermarket to buy three carrots and a carton of soup? You notice a couple of new lines — something photogenic and organic looking that’s bound to be terribly good for your children, so you chuck that into the trolley too.”
