Hmmm, just read the article, do they scan the tickets to get through the turnstiles or something? I don't see how they can expect the stewards to check all the serial numbers otherwise... I suppose if they're all in one section and there's no others in that section they could chuck people out, but if 1600 have to be chucked out it won't be so easy...

But if they can police it they should re-issue the tickets, load of bollocks either way.
