There are one or two off the street hires in the center at which I am employed in, and they spend most of their time, when they are not delivering packages or PCM'ing, defending themselves from those who were promoted from some other position. I enjoy a good natured ribbing as much as the next person, although I am not a driver (have been a helper a few times but that is not even in the same league as driving) so I keep my mouth shut.
I frequently load different cars on different days, and as an observer from afar, I do have to note that these individuals probably develop a huge resentment because they are looked on with almost constant skepticism and ... borderline disdain. That is not to say all "inside" drivers have this view, but the ones who do tend to take it to the extreme and I can understand how some people would react sharply when even lightly kidded about it after a certain amount of time. And that is not to say that this is how Upstate feels or what not, as he is a grown man and can/does speak for himself; just a relevant thought I had.
Just what I see, though.
