Gloucester
In a blatant plug, I like to think we've got it about right at Gloucester.
What's more, you get a landing fee discount when you buy 50ltrs AVGAS or 200ltrs of Jet A1. The refuellers have to run back to the hut to swipe your credit card because the hand held swipey thing doesn't have a good enough signal...(the bank's fault, not ours!)...but they're a pretty efficient bunch normally.
