Brooklands,
Thanks for that - interesting reading! I am not whinging about the £20 as frankly it was a whole lot cheaper than a smoking hole in the ground.
It is merely the principle that I wanted clarification about.
As stated ATC or VAS can have the twenty for their next section "do"!
Why don't one of you Flyer forumites invite that helpful Sqn Ldr ATC'er to partake in the joys of Pprune?
