Patience is a virtue

My school has a tiny computer lab, 7 computers or something like that. Right before class it is always pretty busy, but I'm usually able to get into a workstation in about 5 minutes. Last night....I totally lost my shit. People were checking their personal e-mail, and printing like 500 page documents on the one little printer. All I needed to do was a quick finalization on my paper...10 minutes tops. It took me 30 minutes, 50 sighs, loud gum popping and constant toe-tapping to make someone finally get a conscience, close their personal crap and LET ME WORK ON MY SHIT!!! I dont often lose my shit, but I lost it yesterday.
