Americans in general do not maintain their cars the way they should, and there are plenty of bad
drivers out there who stretch the limits of automotive engineering every time they sit in a car. Beyond all of
that, parts occasionally do fail. It’s a fact of life. Of course, your customer does not necessarily want to hear
that after sitting on the side of the road for three hours waiting for a tow truck. He definitely doesn’t want to
hear that the $642 water pump that he had installed last summer is bad and not covered by the 4,000-mile, 90-day
warranty you gave him when you sold him the job many months ago.
