People would bite gold to check it's real (softer than many other metals). Looks a bit naff when an Olympian does it IMO. The medals aren't real gold anyway (silver, coated in gold apparently).
Anyway...

Incredible.
but why do the silver and bronze winners do it? 
Definitely! Not belittling Yorkshire and their finest, they have done us proud!
I was quite shocked they're not gold. With the amount of money available to the Olympics, real gold would easily be affordable. Not sure about 50p size, a bit too small, even in real gold.
Well it might not be completely made up. Say they damaged a door, the staff point a gun at them and say they can't leave until they've paid for the damage. They pay an amount chosen by the staff. That's not exactly doing things by the book is it.
You're late, and you've forgotten the keeper.
