There was never a legal requirement to wear them on open platforms in England.
I know I’ve said this before but I really can’t seem to work it out and would love to get an idea of the psychology behind it.
There doesn’t genuinely seem to be any pattern that I can make out of gender, age, frailty, skin colour, clothing, time, job, location, or anything else. Indeed, on Wednesday I was on a train and before I got on (and after I disembarked) there was a man (a decorator Id assume as he had paint rollers and other similar type equipment poking out of a bag covered in specs of paint) and at no point in the journey did he wear a mask. I boarded the same train yesterday and he was there in exactly the same seat and part way through the journey he took a fabric covering out of his pocket, picked off the bits of pocket dust, and put it on. The train was less busy yesterday than the day before.
