On my way to the restroom, I was stopped, or rather accosted, by a stranger who said, "I need you to make some copies for me."
Er, who are you and WTF?
Turns out it was a professor NOT from our school teaching a class in our building. I directed said professor to our school's Service Center.
I'm not your copy monkey.
Also, just because I look like a student, it doesn't mean you can order me around, jerk-off.
