He was probably wearing one of those N95 respirator masks. Now you know why heathcare workers also wear those plastic shields over their eyes. Heck, my dentist has been wearing one of those shields for at least a couple of years. Wearing a mask is just one tool, just like gloves, gowns, washing hands, sanitizer, etc. We can only decrease our chances, not eliminate them, unless you and anybody else never left home and you didn't collect your mail, or have home delivery of groceries, packages, etc. Obviously, not going to happen.
