Most of these come from supervisors in a factory who just want production out the door. I know there sarcastic answers, but, after a few per day from the same ones week after week, you think they would get a clue.

Question: Can I help you?
My reply depending on time of day, "Sure, climb up there and....."
Then the direct answer, "No" or "Im sure your not qualified"

Question: What's wrong with it?
Answer: Well, what is it "supposed" to do?

Question: You ever done that before?
Answer: Nope, hope I get it right.
