If you were called by your superior while in the middle of fixing a piece of equipment and asked to drop everything and move to something that he or she sees as a larger priority, how would you respond?

The one thing I remember clearly was when the engineer took me into the test floor and made a sweeping motion toward the equipment. He said "all these machines do the same thing, they make money." I replied, "except for the ones that aren't working, that's where I come in." He really liked that answer. Again, the rest of the interview was standad fair. Nothing difficult, and no "gotcha" questions.
