Hostility in the work place

I had a co-worker in another department come up to me today with a question about whether or not he could do something. See, we have about 20 computers on campus with a specific type of software and correlating hardware installed on them. Due to the nature of the programs, the regular campus technicians aren’t allowed to service the external hardware nor the connections to the computer. Frankly, it pisses this guy off something fierce. I’ve heard at least five times “It’s just a couple of USB cables! Why can’t I remove them or set them up?” Honestly, if I had my druthers I’d let him but I can’t. Anyhoo, one of the offices with these computers installed is getting new machines so we have to re-install all the software and hardware on the new machines. No big deal. It’ll probably take me an hour or two. Well, this guy, let’s call him Smithers comes up to me this morning while I’m putting stuff in the fridge and says “Hello.” I assume he’s just being friendly and start to leave when he says my name. When I turn around I find a visibly nervous Smithers. So nervous in fact he’s practically out of breath. Wants to know if he can make an image with the software and drivers already on it to save some hassle. We go back and forth on it for a while because he’s not being clear AND he’s being an arrogant ass. When I finally get the giste (he wants to make an image to use for the 20 machines with the software on it and then throw it out when the new machines are done) I tell him he needs to talk to the project manager for the overarching project. At this point he gets huffy about the whole thing. Says he’s just trying to make things easier for everyone. I’m not sure why he’s so concerned about this software other than he’s not allowed to touch it. In all honesty, it probably wouldn’t matter if they put it on an image but I’m not willing to let it happen. In the end, if something goes wrong, I need to know with 100% surety that the software is installed correctly. I just can’t be if those jokers get to monkey with it. Anyway,? what really caught my attention about the whole thing today was how downright scared Smithers was to talk to me about his idea. I don’t believe I’ve ever given him reason to fear me. I’ve certainly never yelled at him or threatened him. Maybe he knew I’d say no but was hoping I wouldn’t. Anyway, I have no idea what his damage is or why he’s so intimidated by me. Probably just that low self esteem kicking in. Poor Smithers…
