Nothing suprises me anymore. Before my parent we JWs they had friends who did this , they would all put their car and keys in a bowl or hat and who picked out keys that is who they went home with. My parents claimed they never particiapated in this game.
So its not hard to believe witnesses do it too. There is as much sexual misconduct in the organization as there is outside the witnesses. Witnesses just are good at being sneaky about it and hope they don't get caught.
I am not saying this is the norm among witnesses but it does happen a lot.
