>Mate of mine was in a long supermarket queue the other day, just ahead of a young mum with an out-of-control child.

REALLY obnoxious brat. Pulling things off shelves, screaming, banging the shopping cart against my mate’s legs.

Mate politely asks Mum to get Brat to stop doing it, Mum politely asks Brat to stop doing it, Brat continues doing it with increased vigour.

Repeat a couple of times, after which Mate thinks “Sod this for a game of soldiers”, gets a carton of yogurt out of his cart and empties same over Brat’s head.

Silence ensues, followed by impassioned howling.

And a voice from the rear of the queue…..

“I’ll pay for the yogurt”
