My USA flag mask is nice and thick, to obscure the fact that it's porous AF.

I only (begrudgingly) wear it to doctor offices, on the rare occasions I've gone. My dentist is based and doesn't require masks, but most medical facilities will just go totally psycho if you even look at the door w/o a mask on.

Though I don't really enjoy it, I get a kick out of seeing a business proprietor through their door, past a "Mask Required" sign, pull out my mask, then shake my head and just leave. Somehow, having the mask in hand seems to hit harder.
