I'm not really going to refuse to wear a mask in places where I actually have to, because I can, there's no health reason why I shouldn't, I just don't want to and it's pointless. So I will, for shops, but I won't be doing any 'just browsing' type of shopping because I object in principle to the whole ridiculous business.
Also, because I'm petty, I won't wear one until the day it's mandated. I haven't yet worn one even for a second during the whole of this pandemic, and when I am finally forced into one, I'll take grim satisfaction from knowing it looks as fucking stupid as it really is (my mask is bright turquoise, with gurning emojis printed on it.
