I have been just ignoring the signs (not that I go out much) and nobody says shit to me. The couple times I did wear the things they constantly fogged my shades, generally obstructed my breathing slightly and made me smell my own breath/made my whole face all moist.... The kind of sheep that thinks it's worth the, absolutely beyond minuscule, amount of protection gained from a strong flu, with their cabin air set to internal shouldn't be aloud to have air at all.
