Our man on the scene, Christy Simson, explores the other side of sports, men selling tickets at exorbitant prices.

The offical BOCOG (Beijing Organising Committee of the Olympic Games) line is that all the tickets for every single event at the Olympics have been sold out. That may well be true but the way some of those tickets are being sold might not be approved of by the BOCOG top brass.

I went to the Olympic Green Tennis centre this morning - There were a couple of big matches - Serena Williams was playing and so was Daniella Hantuchova. The stands were absolutely packed - Everyone getting the same view but their ticket prices were very different.

Most of the fans I spoke to who got their tickets through official channels bought them for 100 RMB (US$14) which is very reasonable for 10 hours of tennis.

A lot of others had 'freebie' tickets - I met three friends of Serena and Venus Williams and a few others with tickets from the IOC.

There is no other way of getting a ticket. You can't just 'turn up' and get one at the gate. And that ladies and gentlemen, is where the 'ticket touts' come in.

You'll find these guys (they are always men - and usually unsavoury) hanging around at any major sporting event. They'll have recieved their tickets from questionable sources and they always appear when time is running out and you are at your most desperate.

With 10 minutes to go - the time had come for a few punters to bite the bullet. Four Danish guys who were desperate to see their heroine Caroline Wozniacki, parted with 500 RMB (US$56) each.

It doesn't sound like much but it is a) Five times as much as tickets bought on the internet and b) it is just under a week's wage for the average earner in Beijing (This according to the National Statistics Bureau. Beijing and Shanghai residents are the richest in the country, and make drastically more than rural workers who average about US$417 a year).

One American tennis fan told me it was a shame that the ticket touts were here and it was against the spirit of the Olympic Games.

I didn't say what I thought which was 'Do me a favour! It's a fact of modern life - These days there's always someone out there to exploit wealthy disorganised sports fans.'

I got in free with my press pass.
