These chasers are spouting off great sums of money for the players if they win... is it THEIR money (bloody doubt it!) and do they have limits to offer (The celebs on the one a couple of days ago amassed £140,000 (!) but lost it all in the final chase)... Just sitting here pondering - don't expect to get an answer really....
Of course its not their money Hippy, and not their decision how much they offer, that will be up to people who look after the books/accounts to see how much tax they can can lose.
