I Think you should try and track him down not because you were in the wrong you weren't but because it'll be a mountain before you know it. I know it's a different subject but I've heard folks give restaurants a bad name because they screwed up their order and when I asked the waitress what was wrong it was something small a cup of coffee or pop but you ask the customer it's the whole order the same thing will happen here it may be a water heater but when he tells others it'll be a truck load then the second person will tell it and it'll be truck and trailer and so on some folks thrive off of this type of thing. Our transfer station here has the red and green light with the weight shown below it the light doesn't change until the numbers stop bouncing .
