"but it is there game on there pc so its no ones buss..."
I disagree. If their quitting causes the game to end so that the other players cannot finish, which happened twice to me in the last 2 days when we were just 2-3 holes from finishing, makes it our business.
If someone wants to quit and it does not affect anyone else's game, than fine.
As for players averages, if someone quits, why not take the holes played into consideration towards the average? That way, the player can quit if he/she feels that their play is off and doesn't want to make it any worse than they just did, but what the holes they did play are counted.
But until the system is fixed so that quitting does lock the system up for other players in the game,any kind of quitting should be dealt with.
