Wow, that's a much better story than mine. The company I used to work for did a LOT of attic fans, so I have surely endured the hell that you have described more times than I can remember.
My most memorable service call was when I replaced a 60 amp lighting main breaker for a gentleman who didn't speak English very well. Our company charged $21.60 for this breaker; a little bit high at the time, but they were paying for the convenience. That, on top of the service call added up to less than $100.00. The "gentleman" refused to pay, so I went to the truck and radioed to the shop. My boss instructed me to go back and remove our breaker, reinstall his and get out. Not so.
When I attempted to re-enter the garage, he came after me with a baseball bat, cursing me and threatening to kill me if I entered his property. I explained what I was going to do and he chased me out into the yard with the bat, knocked me down and hit me with it several times. He then banged several large dents into the side of my van, then went back in the house. Again, I mustered my way to the van to call for backup, only to be told to leave the premises, which I did.
I drove down the street and parked, just trying to regain myself and make a phone call. No sooner did I do this than the radio chimed. It was the office calling to tell me that they worked things out with the customer on the phone and that he said he would pay and that I could come back to pick up a check. I did so, with the escort of a police officer. He was arrested and charged with assault and battery plus destruction of property. I never got the check. I don't know whatever happened to the customer either.
