I have to go with the afore mentioned "when will you be finished", sometimes before you have even put your tool bag down.
"Shortly after you stop bothering me" is not a bad answer.
I worked with a guy who had a great way to get people to get away from him. If they got in too close he would hand them something real dirty and say "hold this". Pretty soon they would decide they had something else to do.
Had a supervisor in a plant do that to me one day. Told him 15 minutes. He came back and I was not finnished, again told him 15 minutes. After 3 times he said but you told me 15 minutes. I said, 15 minutes to fix. I haven't found the problem yet. Did not see him the rest of the day.
