BHX for example charge a pound for 10 minutes. Go over that by a minute and you need a mortgage! That's not a service, that's a simple cash cow
Have you not read the above posts. A charge by the minute is to stop drivers blocking the drop off area with extended stays. The clue is in the name, DROP OFF, PICK UP nowhere does it say car park.
I would be interested in your proposal to keep the traffic flowing?
