Don't hold your breath. Of course, there are times when a deadline absolutely can't be made. It will happen to the best of us. However, all I can see Subzero doing with that attitude is to get his contract terminated. He thinks that because his present "employer" isn't in expedited that it won't happen there, but the first time he tells his new dispatchers what to do with themselves and where to do it, they'll let him go.
I wasn't there so of course I didn't see the situation, but--- the other driver might have been right. Shifting a load from one truck to another on the side of the road just might not have been safe. You may have to maneuver the good truck so it faces the wrong way, then back up to the crippled truck, shift the load and then re-maneuver the truck-- possibly in traffic, possibly in poor weather or at night-- to get it aimed right and getting under way. If you don't maneuver the truck, then you have to hand carry several packages the full length of the truck, possibly on the traffic side. Unless you're on a quiet country road that has five cars a day on it, this could be asking for trouble. I wouldn't want to try this on an Interstate. The idea of being towed to a safe place for the transfer makes a lot of sense.
