Someone posted in the last 100 pages with exactly that complaint, that a 3 year old that was asleep was asked to fix a max covering the nose.
Fine, there's some very small percentage that are. So, again, if that's the assumption, and everyone is assumed to be in a trial. We're back at the slightly small nuance of "people don't like to lie, and this technically makes them lie". That's kind of a crappy rule.
Which really, back to the other point I made. If you're not doing any mitigations including distance while unvaccinated people eat. What's the point to the rest of the rules at all?
So, if there's no point to the rule and they're not going to enforce it beyond hoping people feel guilty, it's hardly a rule at all. Just come out say "We're open, pandemic over!". For people that accept the current levels as good enough, that's 100% true.
