I give a lot of handouts, things I have prepared, (as templates in Amazing Charts) or things I have typed out for them while they wait. Maybe this (and avoiding jargon when we explain things) will serve as a pre-emptive strike and make people feel that they don't need a tape recorder. I am not comfortable trying to explain something, then hearing myself on tape.
I came in a room one time and the wife pulled a recorder from her purse like a 6 gun, sticking it in my face when I was supposed to offer an opinon about a problem on the skin. I couldn't really see the skin or anything else at that point, (all the RED FLAGS waving in the room seemed to block my vision.) I looked concerned at the skin for a time, while I thought about this, and announced very clearly that I was not sure what the skin condition was, and I would give them a list of dermatologists to chose from for this problem. (4'th and LONG, punt!)
