Fireguy, I love that story!
I've seen more subtle variations, most of which boil down to "I automatically jack up my price with "X" because I know it's going to be a never-ending PITA." In the most extreme form, it's "I'd just as soon not have to deal with "X."" (Then, of course, "X" wonders why their calls don't get returned, or all the contractors they find are marginal operations).
