Who knows?
Depends partly on whether the government are doing it for health reasons or economic.
Could be all throughout winter. Could be until there's a vaccine. Could become the new norm (I hope not).
Mumsnet seems to be heavily swayed towards masks. But when I've been to the supermarket before yesterday, hardly anyone was wearing one. If they wanted to they would wouldn't they?
I went to Asda yesterday, most people were wearing them as it was the new law, but many were quite vocally pissed off about it. Lots had scarf pulled up over their face and I saw a few visors. Even 3 shop staff were saying how ridiculous it was.
Popped to the retail park afterwards, shops were dead.
So could depend on whether footfall increases or not.
Will also depend on whether it helps drive cases down.
I'm also prepared that we are being eased into having to wear them in restaurants, cinemas, pubs.
We've been told for months that masks don't do any good. I predict that people will stop bothering before long a bit like with lockdown.
