Ageism?

So you're doing your shopping in the supermarket - Morrisons in my case - and that recorded message comes over the tannoy saying they have this policy on selling alcohol, and not to be offended if you look under 21 and are asked to prove your age, and you think - right, I would be tickled pink if somebody thought I looked under 21! Well, small snippet in the paper over the weekend about a 72-year-old man who Morrisons in West Kirby refused to sell two bottles of wine to, because he refused to provide proof of his age! Mind you, I did my square-bashing in West Kirby 52 years ago and it was a strange place then - seems it hasn't changed.
