It's amazing how aggressive people get with their doctors over this, too. I've had people scream at me and threaten to make trouble for me with the Medical Board when I told them they didn't need the tag they were demanding.
Or if I was on a locum, they would just stomp out and come back the next week when their regular doc was there. I think a lot of docs cave because they're so sick of fighting and being abused about it. (No, I don't agree with that. But your office life sucks significantly when you constantly have to stand up to the agenda people.)
Love the sticker you came up with, rzkenrage!
Is the adhesive permanent, by any chance?
