Parking in the dock!!

I used to deliver to food warehouses, there was one small warehouse with one dock, there was a crown vic parked right up against the dock, I backed up as close as I could to the car, blocking him in, and got out of the truck, the owner of the car stuck his head out of the office door and announced, he would be a few minutes before he moved the car. I said "that's ok, I'm going to use the bathroom and I'll be awhile". I returned about a half hour later and he was patiently waiting in his car for me to move my truck.
