I prepaid for the parking but at the exit the machine by the barrier did not accept my ticket. It took several conversations with, and many attempts by, an operator to get the barrier lifted. Several times the ticket was thrown out of the machine, which meant that I had to reverse the car, fetch the ticket in heavy rain and drive back to the barrier. Also, I find the parking charges to be extortionately high, it is a form of legalised robbery. It has now got close to the point where the parking charges are higher than the cost of the flight, and that includes a hefty Air Passenger Duty. Welcome to Rip-Off Britain!
