I didn't miss it, any more than I missed mandating everyone has to wear a hazmat suit 24x7. Neither would be justified. Requiring people to wear a mask when in a shop is entirely justified. If we stopped most of the infections through nose and mouth then we'd be in a much, much better place, wouldn't we.
The problem is not the people who are reasonable and responsible. The problem is the people who are too rebellious or just too "couldn't give a toss" to follow the rules. It is such people who are responsible for the rise in infection rates we have seen.
