In a neighborhood, everyone knows your name. If Joe the Plumber and Fred the Butcher make a bet, everyone has heard it, and the loser has to pay up, or be scorned.
In a bar, the bartender or server holds the bets and pays off the winner, and expects a cut of the pie as a sevice fee/tip.
Filthy children!
