Professor: I need to go grab something really quick from my office. Can you watch the class while they take the quiz?
Interpreters/transcribers: I'm sorry, no. We can't be responsible for your class.
Professor: It will only take a minute. Just watch them and make sure they don't open their books or anything.
Interpreters/transcribers: I'm sorry, I can't be responsible for what they do while you are gone. You could put a student in charge... But I can't do that.
Professor: But they have already started the quiz.
Interpreters/transcribers: I'm sorry. You'll have to collect the quiz from them, then.
Professor: [rolls eyes] Okay.
I am not your personal assistant!
