Unsportsmanlike?

[Toddy]

Yesterday I was in a tourney that was near the bubble. I was low on chips and was waiting for a hand to play because the blinds would eat me up before I'd hit the money. Im in middle position and the blinds are 2000-4000 and I have about 8200 in chips. 1st 2 people fold and I move all in w/ KK. It goes all the way around and everyone folds. It gets to the BB (20K in chips)and he thinks about it. Then it says that he's requested additional time. He lets the clock run down to 50-40-30-20-10 seconds. So I figure he'll fold. The clock goes down to 4-3-2-1-CALL.. He flips over AA. How bad is that? Is there any need for this?
