• I was once working as a contractor for a fortune 50 company, in their data security department. I was called in for a 2am server crash. There was a tunnel from the parking garage to the building. We were supposed to display our keycard/picture ID at all times (or else!). After I entered the tunnel from the garage via my keycard/picture ID, I put it back in my pocket since it was cold outside and I was warming my hands. I was met at the end of the tunnel before getting into the building by 2 armed guards - they weren't happy (the tunnel is under video surveillance). This is the same company/dept where if you left your desk, and your screen saver wasn't on and locked, you were fired on the spot, and escorted out the door.
