Some people are just horrid, rude, and intimidating to a young female receptionist, but act very with the doctor. It probably isn't worth a recording system, but I'd love to hear what they say. I've told my staff if someone is being rude, to feel free to just transfer them to me.
Had a CEO of a billing company call me and my number automatically forwarded to our crew as I was out of coverage driving between two practices (rural Utah).
Said CEO got increasing belligerent when she was told I wasn't available, and started to trash-talk me. Unbeknownst to her, she happened to get Lori (my Lovely Bride), and that didn't go as planned.
As soon as I hit the hotel that night I Black-Listed said CEO (ALL of her numbers) in our phone system. If you can't behave in a civil fashion on the phone - we don't need to talk.
