I agree with Gil A. Even some of the medical professionals my wife knows at the university she works at don’t agree with a lot of the CDC’s recommendations. I got much more grief from the barber shop owner on his insisting on wearing a mask than the doctor I saw for an appointment in his office. The doctor never brought up the subject of me not wearing one. Most of the passengers I have flown on recent charters don’t wear masks and those that have remove them when I tell them during the passenger briefing that wearing the mask inside the plane is strictly voluntary, and that our (flight crew) masks come off when entering cockpit.
