That's what I do too, but it seems that just about all the stores here are requiring them right now. (I've noticed a few people here and there wearing smiley face masks, so I guess that must reflect their inner feelings a little, anyway.)
Even the mandatory stores have folks without masks. I just hurry in and out. I am seeing a wide variety of fun ones.
I really think folks are sick of the whole mask thing. It’s amazing what a “whole” face can tell you. Covering it decreases any attempt at friendliness.
