Used Signature in the end.
Will try Harrods next time, not out of a desperate alternative but variety spice of life an all that!
No problems, ATC still insisted that I report finals for the concrete - which actually stretched atc's requirement - despite there being nothing in the way blah blah.
Silly charges but as expected for complimentary coffee (may I say how smart you're looking Captain!) and papers.
Then airport feels that it must add a 'handling levy' - still trying to work than one out.
Beautiful day for flying, just gratefull that I wasn't flying 'Die'n'air' or 'Sleazy Bet' with tubes full of tourists - then again, atleast you had aircon!!!!!!!!!!!
