I'm missing something. How is the truck any less left behind if you drive him than if he takes the speedline?

Sorry, but I hate it when people give excuses that make no sense.

I'm a big fan of people SAYING WHAT THEY GODDAMN WELL ARE TRYING TO SAY. It sounds like you are too. I applaud. And I think if he calls for a ride home you should tell him you can't give him one because you have to keep an eye on the truck.
