Fair question. But I would say that makes the person who comes up with the rules, a poor leader. Your own values and morality will determine which way you go. However saying that. It looks like, especially around Manchester, the majority are sacking this mask thing off.
Just returned from a quick trip to aldi. Forgot me burger buns yesterday. I didn't see one person with a mask on. Admittedly, it wasn't that busy. But still. Not one person, other than me. I have a stinking cold, so not inflicting that on others. But it got me thinking, if nobody else is bothering, why should I.
Because if no one bothers at all, we'd all be in the brown stuff.
My sister is a nurse, my wife is a physio, both work for the NHS and do their absolute best day in day out to set a good example. Luckily the majority of their friends are the same (the majority who are colleagues)
Hope your feeling better soon anyway mate and the PCR test you said you needed comes back negative
