Sorry to hear about your ordeal. The masking was very frustrating for me as well. I went to the doctor and the front office staff threatened to cancel my appointment because I wasn't wearing a mask when I came in the waiting room (which was empty).When I said I was exempt, the woman said to me "you are not allowed to endanger my life" (I was 6+ feet away from her) So I put the mask on and when another staff member started to talk to me, I told her I couldn't understand her because I was hearing impaired and she spoke louder. But the next time I said I couldn't hear her, she said " I should not have to raise my voice. " All this was against ADA regulations. I should have complained to my doctor but I didn't waste my alloted time with her.
At a different appointment, the dermatologist assistant would not remove her mask and she sat so far in the corner away from me like I was contaminated. She said she had to wear her mask starting in the parking lot and if she removed it she could get fired. Fortunately when the dermatologist came in, he was wearing a clear shield.
A third time was a more positive experience. I was meeting with a dietitian and told her I was hearing impaired and she was glad to remove her mask.
