A healthcare professional once asked me if I was being careful to wear my muzzle everywhere.
I showed the box my muzzles came in.
The box had a NOT FOR USE IN HEALTHCARE SETTINGS warning on it.
The HCP never bugged me about muzzling again.
I lost any respect for health professionals/experts very early on into the pandemic. I scored on a surgical mask after being forced to wear a scarf or tee shirt to get food. The packaging said the mask doesn't protect against viruses. The ridiculous decrees by these morons are too numerous to cite in any detail, but my favorite experience was the first trip to the golf course after shutdown restrictions were reduced. Tee times were 20 minutes apart and max 2 people allowed to play while walking and no overtaking the group ahead allowed. A golfing buddy and I violated that decree after a couple of holes.
