I did my weekly grocery shopping today at a large chain store, that has the usual mask signs in front. I have been going there pretty much every week, and starting a couple months ago, just wore my mask over my mouth. Nobody said anything about that. Today, since I'm reading about others doing it, I went maskless! I didn't receive any flack, and didn't notice any looks on people's faces (but I was just shopping as usual, and didn't make an effort to observe the response). It was great and I encourage ANYONE who is not afraid of the virus to do it. (now I do have gray hair and a gray beard, so maybe they assumed I got the shot :) )
