what just happened?

so i'm sitting at my desk, doing all sorts of important things such as checking email or reading about a restraining order denise richards has put on charlie sheen, when this guy walks in (not that works here, but does like maintanence or something) and just puts some paper on my desk. he proceeds to walk into the mail room in the middle of my sentence asking what i am supposed to do with said paper. he walks back out and sort of just stares at me when i ask what he wants me to do with this paper, or who it is for. he just says, "sign it." refusing to answer my multiple attempts to figure out who it is for. he then stands by the door waiting for me to let him upstairs...so weird.
