I tend to shop at self check out stores, and have headphones in when the mask-holes at the front try to get antagonistic with me, I don't even make eye contact with them as I don't acknowledge people with a lack of a backbone and conduct my business. The occasional times they follow me and raise a fit, I tell them I have a medical condition, I'm too attractive to wear one, and I dont subscribe to marxist ideology. The one time the manager threatened the police, I said go right ahead I'm sure they'll rush right over here to stop the big meany head who isn't wearing a mask, bought my shit and left without issue.
