I said it before and I'll say it one more time. The winner pays the vig.
The following two paragraphs are taken from the January 1983 issue of GAMBLING TIMES, from a two-page article written by Bob Stupak. The article appears on page 64 and 65. The title of the article is called "The House Edge." If I get ambitious, maybe I'll scan the entire article and post it on my website and then post the link here. (It's simply too long for me to re-type the entire article by hand.)

There are two inter-related concepts about casino profits that most players, and even many longtime casino executives, don't really understand. First, players are paying the house edge only when they win - never when they lose. Put another way, you might say that the house makes money not on customers' losing bets but on their winning bets because the house pays slightly less than the true odds on those winning bets.
If a fellow comes in and makes one bet for $1,000 on the craps table and loses it, he pays nothing for it. But if he wins the bet, he should get approximately $1,028 for his $1,000. Then he would be getting true odds. Instead, he wins only $1,000. So by winning the bet, he pays a $28 vig. By losing, he doesn't. Customers are often a little flabbergasted when I tell them, "I only make money when you win, not when you lose." The may be hard to believe, but nevertheless it's true.

Me again.
The winners pay the vig. The winners pay it because they have less in their pocket than what they should have, after winning. The reason they have less is because they paid the vig. The loser simply lost a bet.
It is very difficult for me understand why so many players here just can't seem to understand this simple concept once it's explained to them. As Bob said above, even "longtime casino executives" don't really understand it, so the initial confusion is understandable
(Of course, it is also difficult for me to understand why so many players play parlay cards and then wish to hedge their bet on the last game, thinking it is "guaranteed money.")
