There are masks, and there are masks.
I see a lot of folk in supermarkets with bandanas wrapped over their chins and bottom lips, unsure of the purpose of this other than to gain them entry to said supermarkets.
Unfortunately people think that if they wear a face covering they no longer need to distance themselves, or wash their hands.
I have a supply of the best rated masks from work, sadly no one told me how to use them until my wife saw me put one on and told me it was inside out. Duh!
