I irritated the safety man at the charter bus company I worked for a few years ago. He had some students trying to get a 40' MCI coach through a serpentine. I came in with one of our new 45' VanHools, went through the serpentine forwards and backwards, kept on backing into my parking space and shut it off. He was somewhat hot when I opened the door. Told me a couple of his students wanted to quit right then.
When I see someone trying to back a Monaco or Prevost in some places I have to stifle a strong urge to ask them if they'd like me to park it for them. I can't believe some of those people.
