This is anecdotal, of course, but my son works a counter at HEB, a large grocery chain here in TX where masks are required. His observation is that 80-90 percent of people, when conversing with him, move the mask down to expose their mouth. For those that do leave their masks on while talking, the act of talking causes their masks to slip down, exposing their nose. Both of these acts cause them to touch their face profusely to readjust and move/replace the mask.

Very few people have the discipline to fit the mask properly, and then leave it alone, which would be the only way they would be truly helpful.

Masks are making things worse.

I second your son's observation. Another observation I have is people doing physical labor like stocking shelves have their masks down or at least below the nose.

Then teach. It’s not a reason to stop a practice of abatement.
