A few years ago, not paying the ridiculous fee that some doctors offices said they would charge you to fill out a form! I was beyond insulted, and filled it out myself and went into my appointment and pointed to the line where the doctor needed to sign. He had no problem with it.
I had that "I hope I DO pay you that stupid fee!" attitude. They gave me the evil eye, but there was nothing that they could do about it.
I think they are just waiting to see if anybody is going to protest the fee.
