Yes I’ve been wearing it for over a year I’ve had a little bit of opposition once in a while and I shamelessly pretend I can’t speak point to the badge and mouth the words .. I have a medical exemption! but 95% of the time I’m treated kindly and waved in , as I said a few times I’ve been stopped some goofball comes down to the grocery line carrying a mask and they try to give me one or some manager tries to approach me but once they see the the badge they leave me alone. I laminated it and wear on a lanyard ..I’ve never worn a mask and in San Diego where most people wear two ..that’s pretty good nobody goes without a mask out here it’s bizarre.
