Worst Case Scenario

Many people have plans for a worst case scenario. I for example have a 12 week program designed specifically to survive a zombie on slot.
Some people save money just in case there job goes under. Some stock pile food against Armageddon. Others keep a few extra pills from there prescription so that if everything goes south, they can just go south with it.
I do know one person though, who doesn't have a plan in case of a worst case scenario. His plan is to be the worst case scenario.
Not long ago, a discussion was had near me. And since it was in my general vicinity, the Noid was involved. He was asking if he could just leave early whenever he felt like it and our manager had told him no because that would constitute job abandonment since he would be leaving before his work was done. Noid wasn't content with this so he explained that he didn't need to be here the last 15 minutes since it was set aside as a clean up time and he had nothing to clean up. His manager then explained that he could just take away our clean up time since it seamed we didn't need it. This was a bit upsetting for most of the people in ear shot as we actually need this time to ensure that we don't get stuck at work by a last minute call. There was some complaints to the affect of smacking the Noid if he cost us our last 15 minutes of safety.
As anyone who has met the Noid knows, confrontation is not the easiest thing for him to handle. In an interesting moment of in site, he blurted out "Well, worst case scenario, I come in and shoot all of you." I then turned around and asked why the hell he would be shooting me. He answered that it was a general threat and that he would be selective of who he shot.
I could go on and on describing the following 15 minutes of how this conversation went and how management handled this. but I prefer to just end with this statement. It is common knowledge around work that Noid packs heat at all times. If I see him at work, I will start going home sick any time he gets upset.
