I recognize the level of choice I have in it, but like you mention, it's the other worrywarts - if I'm willing to be <2m away from someone, but they are not, it's still the same...
To be honest I figure it's going to just be obvious as time goes on. When the pubs re-open in the UK I'm just going to assume that anyone there doesn't care about this nonsense, otherwise they'd barricade themselves inside.
