My partner Ed and I have a routine when we perform routine inspections and maintenance.
One of us will deal with the customer, handle the paperwork, and carry the tools, while the other one handles the actual work.
I prefer keeping my head buried in work, so I leave Ed to handle the client relations. Ed has a way with people, and has gotten very good about up-selling them to a higher service plan. Last week Ed and I were on a service call to a house with a couple of really big dogs. These were monster dogs! While I busied myself with the HVAC inspection Ed tried to keep the dogs from messing with me. One of them bit Ed right on the hand. I canceled the HVAC inspection, grabbed my tools, and immediately drove Ed to the emergency room at the hospital. The next day the client called me back and had the nerve to ask when I would be coming by to finish the HVAC inspection. I calmly told the client that none of my HVAC techs would ever come to his house. I was canceling his annual HVAC service plan, and I might hire a lawyer to sue him for the medical bills, too. The man claimed that Ed must have done something funny if the dogs bit him. That settled it, and I started yelling at him! I told the man that my HVAC company would absolutely be suing him in court for the medical bills, and that personally I thought he deserved whatever he had coming to him!
