I've said this elsewhere, but also possibly here, so apologies if I'm repeating myself. Also, I'm in Wales, where some sort of sense appears to still prevail...
But my take on this is that I am going to carry on wearing masks in public places, regardless, for two reasons. Firstly, because I think that the government approach is now as far away from immunological reality as it has ever been - and that's an achievement in itself. And, secondly, on the basis that if people who couldn't give a fuck if twats came up and started giving them a hard time about mask-wearing keep on wearing them, it might encourage other people to carry on wearing theirs.
