Is 50p to spend a penny acceptable?

Would you spend 50p, to have a pee? The Nolan Show was contacted by a listener who brought a Youth Group with over 50 kids - to Planet Fun on the Boucher Road. He was then outraged to discover the travelling fun park charges 50p per pee, leaving this punter to pay almost £40 to use the toilets. He also claims the member of staff manning the toilets refused to let 12 year old girls use the loo - because they had no money.
