"walk into the room with a predetermined pitch that they're determined to stick to, things usually end badly."

True for sales (as I see someone else below also points out).

I'm reminded of a time in the past where I was purchasing a high end typesetter. 6 figure purchase in today's dollars. The salesman kept hitting on the point of the large font collection that the company had over and over again. I kept saying "what's really important to me is your service program". I couldn't have been any clearer than that. (He didn't have to dig for the hot buttons - I delivered them to him on a silver platter).
