While I don't pretend to know the answer to the question, "W.W.J.D.?" I can definitely tell you what I would - or wouldn't - do for a Klondike bar.
Would you stand in a long line to get something for free, even if you weren't quite sure what it was?
Would you be willing to press a button 5,000 times or bow in front of a big machine in the middle of townsquare?
Apparently, some people would.
