I would PASS....
The statement " dont crap where you work " is often the first thing one must think. The stories I have heard!
Well, nevermind that.. I have a better story.
A girl from dispatch and another girl ( soup ) got into a fling with a few drivers. It ends up the girls having an orgy with 4 drivers. Of course no one ever used a condom. The girl from dispatch ended up getting pregant, thusly doesnt know who the father was. This is, might / oftenly, what you will deal with / end up with.
Drivers are stressed beyond thought, most of them have taken up means to subdue those stresses. Whatever it might be could end up you having to deal with it, whenever you like it or not.
The best advice I could offer you, DO YOUR SHIFT AND GO HOME!
