WOW!!! This thread got a lot of action!
Smash, I think this is a little like the football wager, "Team to score three consecutive times". The uninitiated get fooled as to which side to take. I believe you are in the right in "booking" the bet rather than making it. (I also get the feeling you thought it should be an even money wager.)
That being said.........you may have killed a golden opportunity.
I can almost promise you, if you would have offered these guys even money on this, they would have still jumped in with both feet. Let's face it.........guys get two,three, or four hits all of the time! These guys would have been having a hard time choosing which guys to play on a given day!
(Kind of like the fist time you saw a parlay sheet and said, "You mean I only have to pick three of these games to win?")
Once you start slaughtering the sheep at even money, they will start to lose interest. THAT is when you say, "Okay.........I'll give you two times your bet when you win." And you regenerate their interest!
