You can learn a lot about your coworkers by how they respond to an obvious question.
I've been imaging PC's -- P4's of the HP/Compaq variety -- and then sticking a couple gigs of RAM in them to send out to other branches.
At one point, I asked one of my coworkers, "What are these people doing that they need 2 gigs of RAM for?"
He responded, "That's MY question. They are fucking bitches who whine all the time and get whatever they want." The tirade continued for some time.
I asked another coworker the same question later, and he said "You'd be surprised."
I responded, "Well, actually, I would, because I'm the one installing software on these computers, and I don't see Vista or Photoshop anywhere, I just see Office 2003 running on XP."
The first guy is honest but volatile. The second has a stick up his ass, never questions anything, and expects everyone to do everything in a very specific way.
