I don’t have any advice because the people around me who don’t wear masks just have too much power and I risk getting banned from the grocery store (for instance) if I harass them. All I want to add is that the first time in this pandemic I saw someone order someone else to wear a mask was at a doctor’s office a month ago. It was an employee speaking to a patient, too. The patient was actually chill about it and complied. The employees there nonetheless take off their masks the moment you turn your back. It’s the only place I know of where I live which makes any effort to enforce masks.
