I've seen the same - and the people moaning to their local supermarket or bus operator on Twitter about not customers not wearing face coverings, are probably the same people who were too scared to come out because it wasn't mandatory for face coverings to be worn.
But they're perfectly happy for people not to distance because they're wearing the golden bullet tea towels.
During the panic buying I read an article by a behaviour psychologist, who postulated that the reason for that was because *a reaction* made people feel like they were regaining some control of a situation which they felt they had lost control of.
It might have been a perverse and irrational reaction, but it made them feel back in control of the situation. More and more people then copied it for various reasons until we had a full-on frenzy, people prepared to fight with each other over a pack of toilet rolls.
We now seem to be going down the same road with masks. Another stupid measure which some people latched on to, in many cases without realising or understanding the rationale behind it.
It is extremely concerning how a bit of fear can affect rational decision-making. It also shows how an element of society is rather unpleasantly authoritarian towards others.
