I like the Czech pragmatism. Obviously it is not perfect, but anything that obstructs droplets even a bit is helping to flatten the curve, and that's what you want right now. This is one of the most reasonable and easy and pragmatic rules I have seen so far. It seems clearly superior to telling people, because there is a shortage, that masks are not preventing an infection, implying that they don't help.
