Lets say its winter and cold.....a customer calls you for a pellet stove repair. You show up at their place, get inside, you notice that hey, this place is infested with fleas! Now, not being a animal person, I don't have any at home, nor do I have fleas. Being somewhat cognizant of the diseases borne by these little fellas, and their propensity to infest your own clothing, end ergo, your own domicile, do you folks feel the technician is justified in packing up and leaving (without fixing the unit), and basically requesting that the folks call back when the flea infestation is taken care of? Of course no charge for no work done, so, the service call price is a nonissue..... What do you guys and gals think?
