Why would anyone o through trying to bribe there way into a lounge? How uncomfortable and awkward. Many business people will hold multiple bookings, although I recently had trouble with this at CDG and simply wait in the lounge until the have to decide which flight to take.
Some others have stretched this practice, by purchasing flexible business class tickets to allow lounge access then simply refunding the ticket and taking original flights... Equally circumspect and not sure how this would work at CDG.
