I met some guy recently who told me that he has a ticket for the Olympics event in Sha Tin. Though he's bought the ticket for like 100$, he's quoting 500$ for it. I am not averse to paying that amount, but what I really want to know is whether I can really use someone else's ticket to gain entry there. I don't want to spend money, get up at an ungodly hour and go and stand in teh queue for hours just to be sent back home at the entrance. Kindly advise.
