Re the guy (George) with the £50,000 bet. My guess is that if he has the £50,000, he doesn't really need the £162,000. He doubtless has money as the story says he has travelled the globe following Federer from tournament to tournament.
That sounds about right about, I forget just how many there are out there officiating!
I hope so Ken! Lucky man to be able to do that. Seems a lot of speculating for not a huge amount of accumulating. I'm not really good with betting though.
You have the 'Chair Umpire' and up to 9 line judges = 10. The match referee does not actually officiate until called upon to settle a dispute or suspend play owing to bad light or inclement weather.
