Plus, too many people wear a mask wrong, as in below the nose, or have one that is ineffective, such as just tying a bandanna or some such which is open at the bottom.

and bars are the most obvious spots for exposure. Canʻt eat and drink with a mask on. Also family parties, where everyone lets their guard down.
