With out a doubt the worst place i have been is belfast city I waited over an hour for the fuel and had to keep putting the IFR flight plan back untill the tower controler got as sick of this as i had , so he cleared me to taxi to stand 1 at the pax terminal knowing full well that in 20 min an airliner was due on stand ,the ramp people went balistic ! but i refused to move untill the fuel turned up.........funny how the truck only took 2 min to turn up.
