Oh, boy, are you ever spot on about that! THEY know the right ways to go because they're the "professionals."
Of course we need truckers to get essential goods where they need to go, but the ones I have known personally are often full of themselves and not willing to see another person's point of view. I can only imagine what you have to go through, and you have my admiration. Hang in there!
The ones I meet usually are too full of themselves to bother listening to instructions.
