Sad to see some of the comments on this thread.
Unless someone is stopping to ask someone -WHY- they are wearing a mask - there’s lots of presuming about it being due to COVID-19.
Allergies, particulates due to smoke, etc are all valid reasons to wear a mask.
But many posters on this thread just make the assumption it’s due to COVID-19.
That’s probably due to either ignorance, willful ignorance, or perhaps low intellect.
People making assumptions without asking someone why they are wearing a mask aren’t intellectual titans.
In 2019, I can count on one finger, the number of people who wore a mask.
