MTT Heads Up Moral Dilemma - What's Your Move?

[FakeKramer]

I just had a friend win an MTT on Party Poker today (he's not a 2p2er to my knowledge). Anyway, when he got heads up, his opponent disconnected. My friend said he debated whether or not to sit out and wait for him to return, but ultimately just stole his blinds until all of the chips were his. I don't necessarily fault him for his actions, but it did make me a little curious what you guys would do. I'd like to think I would sit out, but I'm not really sure if I would when push came to shove.

Poll Question: If you are heads-up in an MTT (that carries standard payouts) and your opponent disconnects, would you sit out and wait for him to return or take advantage of the situation by gathering his blinds while he is gone?
