Nothing wrong with doing any of those things--IF and its a BIG IF--They TRULY are happy with the result.
I've done things in the past for customers that assured me up down and sideways they would be happy, and guess what? They weren't! But they wouldn't admit to their friends and family that it was THEIR call would they? Of course they would! -NOT They would never bad mouth the builder who was the last guy to touch it would they? You betcha. Now on the flip side of this coin I have had customers who were very happy with their mean sounding , NO power, NO efficiency engine but they are few. Of course there are exceptions to every rule but this is the toughest part of this whole deal. J.Rob
