I have taken a page from Alan's thesis from Progressive lenses, which one do you use. He said:
While I am an advocate of consumer satisfaction and wish to accomodate the buyers desires always, I am still acting as the consumers agent, and reserve the right to smash 'em over the head with a mallet, dismember their arms and break their legs if they don't pay heed to my advice when I say.....NO!
How many people have you had where you wish you could smash them over the head.

I had one that I kept going round and round with, she kept saying I don't understand why can't I have what I want. Finally I mentioned priced and her english miraculously came back. I was with her over 45 minutes. She was one of the tuffest people I have ever had to deal with.:bbg:
