Even if poor attitude leads to the lose of a lot of good regular customers? I find that very hard to belive and would love to see the data on that. Simply because that's what were talking about and noting more.
You would actually like data on the fact that weeding out difficult customers is beneficial? hehe ok, I usually don't work pro bono but here is a example just for you:
Go back and read these two huge threads about a customer that wanted an alternative payment method than was provided and a company that tried to help them (bending the rules) and got shot in the foot for misplacing one check (in the middle of a move) out of god knows how many orders now.
The original poster is a member of this forum and most of us here were aware of TV's move/internet problems and huge back orders a simple search could have shown them what was going on. Instead they chose to make a beware of post. Not a customer any company would want or need.
Example enough?
Also what is wrong with being cocky? I'd be cocky too if I owned the best damn juice site on the planet!
