I was talking to a mate of mine in the pub last night who was having a major moan about Stansted.
He went to pick up his daughter at 1am from the express set down and pick up lanes making sure he didn't enter it before she was outside and waiting.
He said due to the vast numbers of passengers and the length of the lane it took several minutes before they could find each other. He then had to queue to get out. When he paid his £2.50 the barrier demanded another £2.50 as he was now one minute over 10 minutes. It took another minute to find the extra £2.50 by which time the machine demanded another £2.50 as he had now been there 12 minutes. Yes, Stansted charges £2.50 per minute after the first 10 minutes. At this point he rang the buzzer as he had run out of money but it was engaged.
He was eventually let out without paying any more money but it left a bad taste in his money and wallet.
