You can just look up your ada rights and tell them you have a medical condition which prevents your from wearing a pussy badge, aka a mask. Just did this successfully in my local Costco. Was harassed by multiple employees but just ignored them, told them I had a medical condition and went on my shopping trip.

Never ever wear a mask. It legitimatizes the fake virus and gives off an apocalyptic vibe. Our God Emperor himself has never worn a mask.
