On my way around the shop, I saw their security guard tell a shopper off for not wearing a mask. Absolutely fine and correct.
Then when I was being served at the till, the same security guard was moaning to the cashier about the guy not wearing a mask. Except throughout all this, the security guard wasn't wearing one either!
How can he possibly remonstrate with someone not wearing a mask, and not realise he has just undermined his whole message?
Also I wondered why the guard wonders around without a mask on - hardly good for the shop's attempt to maintain covid safety.
