Does he credit the amount towards your bill if you have him do the work? I know of some body shops that do that with estimates. When I complained, one of the guys told me that they can easily tie up a half hour in an estimate, yet many times they don't get the job for various reasons. When you multiply that by x number of estimates per day, I guess it adds up. Still don't think it's right, but I guess I might fele different if the shoe was on the other foot.
