Probably yes I'll be put off -- because the whole reason is to remind us all to treat each other like toxic waste & to minimise interactions. I'm not a recreational shopper, anyway, so I know I don't matter. Still, it's an extra reason to think harder about "Do I really need to go to the shop?"
I have read in several places the argument that masks are a great thing if they cut down on people going out, and that therefore creates more social distancing. Some people want face covers to be mandatory precisely to achieve that.
I had a little tirade today about the govt's transparent strategy in their messaging today. They will talk a 'guilt' line but then handwring that into the narrative "The problem is that some people just won't do the right thing unless they are told to". Both Gove & BoJo are spinning the start of this narrative out today. It's how they want to get support for mandatory face cover wearing.
