You can do more than steal JUST computer parts! Take all the office supplies you can get your hands on, and not just from your own office. If you're walking in a corridor and see an empty office, no co-workers in site, then just let a stapler quietly slip in to your pocket. Well, that might be a bit conspicious, but pencils, pens, paper, it's all good. AND it's free. Seriously, it'll be awesome. And if you're caught, just shrug. What are they gonna do, FIRE YOU!?
