Answer the question "Mac or PC" with "I don't care," and then come back 10 seconds after I check you into a Mac and ask for a PC. Dumb.

Give me sass when I tell you to get out of the classroom after your class is over.
Act like you're special because you're a senior CommDesign major or Interior Design major. Or whatever major because you aren't special, period.
Get pissed when there is a line for the CommDesign plotters, insist that you be switched to the Interior Design plotters, throw a hissy fit to my boss when we don't let you break the rules, have him tell you that you can use then, AND THEN decide that, yes, they're shitty, that's why you get better ones, and try to get to the front of the line for the CommDesign plotter because you're "in a hurry."

Move to a different computer, without telling us, when your computer has an issue or *gasp* it's an iMac on the formerly PC side of the classroom.
Stay 15 minutes after closing, then after I politely ask you to get out, and that I have to be back at 7:30 AM to open, say "Well I have to be up earlier than that." and then leave in a huff without even thanking me for the extra time and my loss of sleep. Rude.
