Well, you illustrate the difference between an airfield run to accept traffic, and an airfield run by former ISO 9000 quality managers
Speaking of "PPR numbers" this reminds me of Bournemouth, where the "handling" is a man with a mobile phone who claimed to me (face to face) that even aircraft going for maintenance must go through him.
If you forget, as in fact nearly everybody going for maintenance does, ATC ask you for your PPR #, you reply you haven't got it, and they let you land and taxi to the maintenance company..... no big deal.
