Should I tell him?

This reminds me of a place in Houston I delivered to 2 years ago. I get told to go to a dock on the far opposite end of the facility from the office and wait until I get a call about my bills being ready before leaving the dock (even if the light is green). I back in, sit there for 3 hours with a green light. It finally turns red and I continue to sit for another hour before they even start unloading me. 4 hours later, the light turns green again, but no call. I sit for another hour waiting for this call. Finally, I decide to pull away from the dock, check to make sure the trailer is empty, then close it up before driving back to the office. They tell me the bills still aren't ready. When I ask how long it will be or when they will be ready, the guy I was talking to says "it's not my problem" to which I say "it will be" as I go back outside to my truck, go back to where the docks are at, and park sideways across a dozen or so docks. I'm a perfectionist when it comes to parking, so I had to wiggle around a bit to get the truck and trailer parallel with the wall and as close as possible to it. Before I could finish perfectly parking, I get a call saying the bills are ready! They didn't think I'd do it, or waste my own time with it, but jokes on them! I get paid by the hour when at customers and shippers, so I'd be more than happy to take my 34 right there.
