We have people bring us a push mower they bought at big box store in to work on and get upset when we don't jump right on it and get it fixed for them. When I have a customer who bought a 10K commercial mower from us and brought it in for repair who do think gets theirs fixed first. We take care of our customers first. One thing we do not work on is pressure washers that have no pressure. If it is engine not running we will fix it. No pressure pumps usually have one of two problems. It either froze and busted or they left water in it and the cholerine oxidized the aluminum parts of the pump and it is toast. You waste time looking at it and give them an estimate and they say they don't won't to spend that much money on it and you are stuck with the pump and no pay for the wasted time.
