They have guards at the clinic and toss you out for not wearing a muzzle. These girls would get fired whether legal or not. Oregon is an evil demshevik run state.
Happens in Florida also at places like Quest Diagnostics. Went for blood work had mask in hand, but not on, went to kiosk to check in and since I didn’t wear mask the “guard” in hazmat suit was going to call and have me escorted out, but I put my mask on since I needed the blood work. Hospitals are even worse I hear.
