I've noticed you using this word "flimsy" a few times. If you're referring to those blue bibs that I see some people wear, then they're OK at catching potentially contagious droplets of spit, phlegm, etc. that may pass an infection onto someone else. They can reduce spray, but of course, they're not going to be as effective at filtering aerosolised particles as other coverings. Should there perhaps be a "standard" agreed on by the powers that be if they are to be effective to a certain level?
There are a number of papers and
studies looking at the use and effectiveness of face coverings (not necessarily N95-rated ones) for controlling and limiting the spread of disease. If there was sufficient evidence to the contrary, then like others, I may feel sceptical about wearing them. But today and come Tuesday, if the situation I'm in calls for wearing a "flimsy" piece of cloth (I'm very selective about the ones I wear, actually - blue surgical masks aren't really my thing) then that's what I'll be doing.
I really don't want to have a major falling-out with people here, so I'm going to apologise if I've caused any upset - you may have noticed that this is a particular... topic... that I have strong feelings about, as many others seem to as well. I can only ask for your forgiveness if we've landed on opposite sites. And, to use a fairly cliché phrase again,
"On this matter, my friends, I'm afraid we're just going to have to agree to disagree."
