Masks are in short supply. They should have been recommended way back when this started, not now. It has always been a good idea to avoid sneezers, push buttons with a tissue. The precautions should also be reducing colds, " other" flu, all the airborne diseases
A side note; I see some restroom doors propped open now. My preference, being male, is the ones with just a blocking partition. Go in let the automatic eye flush and leave and never touch anything. I feel for women who cant pee this way.
Maybe the mask proponents should look at the defecating on the street in some cities.
I do wear a mask, dont sneeze on others, and am discrete about picking my nose. ,
