The mask issue is quite controversial. Frankly, I doubt they do much good, based on the evidence I read. I do wear one when I'm in a store, mostly to make the people around me feel more comfortable. I noticed today in the grocery store that I could smell the bread while walking down that aisle, so I sort of doubt the mask is protecting me from anything more than an infected person sneezing or coughing directly on me. I do find that most people are respecting the need to give others space, which is the most important thing, in my humble opinion.
