Art,
I can confirm that it is not unknown for "Police Management" to discourage the use of, particularly large, civil airfields. In a past incident where we had to refuel at a large but not particularly busy airport in the "North of England", the unit was billed almost twice as much for the associated fees than we were for the 250 litres of fuel that we uplifted - which included Navigation fees, "Runway Fees", Handling fees, Landing fees and Parking fees. We've not been inclined to lift fuel from there since.
