I was in my local small Tesco waiting by the till when the girl assistant let out a tell; two young male assistants rushed out of the door and up the hill, returning a few minutes later with an armful of stuff each. The girl had spotted a shoplifter, the third that morning; they know how they operate and what goods they target, The men rushed after him and he threw his pilfered goods at them and climbed into the getaway car. They staff are mainly young and active and disgusted at the regular thieving; they are warned not to tackle anyone, but making a commotion and giving chase usually scares them off. They had the car number, reported it, but no follow -up.
And 'working -class culture' has not always had a supply of 'things which fell off a lorry'.
Don't dignify theft by pretending the working-class do it.
