Coughs and sneezes, or common breathing are the culprit?

Also, what about the studies that claim up to 20 % less oxygen? How do you trade that off?

I do appreciate you’re not one of the outdoor mask wearing fools.

None of the above. In the case of the church choir, singing. In the case of the salon, masks stopped the spread from talking.

As for 20% less oxygen, I can believe it. Wearing a mask is not pleasant and I have to consciously breathe deeper all the time.
