More lack of common sense

I missed this story which surfaced about a month ago. How old does the gentleman above look to you? 52? 62? Well actually he is 72 but clearly over 21

According to the BBC "Supermarket staff refused to sell alcohol to a white-haired 72-year-old man - because he would not confirm he was over 21. Check-out staff at Morrisons in West Kirby, Wirral, demanded Tony Ralls prove he was old enough to buy his two bottles of Cabernet Sauvignon. Mr Ralls asked to see the manager who put the wine back on the shelf. The grandfather-of-three said he had refused to confirm he was over 21 as it was a "stupid question."

Mr Ralls, a retired insurance firm regional manager, said he expected the store manager to resolve the situation but he was disappointed. "I felt like saying 'What do I look like? Are you a fool?' "He picks up the wine and, in the manner of a child taking home his ball, says 'Well, we won't serve you'."

The pensioner abandoned his shopping on the conveyor belt and left the store - but not before demanding a complaints form and phone number for Morrisons' headquarters.

I realise that retailers have to be careful but somewhere along the line surely there should be an element of common sense in deciding whose age needs to be checked.
