Our favorite AZ Costco employee is a awake. She hates the mask and calls it the “cooter” virus.  She said you don’t need to wear it if you have a medical condition. Next visit, no mask, I have a medical condition, no questions only rolled eyes.  I got dirty looks throughout the store, but I can give two shits what the sheep inside want to believe.  Don’t give in, show the others it’s not necessary.
