Sean may well applaud the winners - he gets paid his fee whatever the outcome. As I've said before, if we were told that the Chasers didn't get paid if they lost, then that would really spice things up.
As it is, the Chasers have no skin in the game.
Yes, they do seem competitive (some more than others), but my point is that it doesn't really matter to them what the result is, as they still get paid the same.
