I was a lot less happy when they diverted into Madrid to pick up a first aid kit and sat on the ramp for the best part of two hours because somone failed to get the fuel truck to the aircraft.
Madrid is a law unto itself and not the worlds most efficient airport!!
I can assure you that the bowser was ordered - its one of the first things pilots think of. Ops will of already pre-warned Madrid BEFORE the aircraft landed and the handling agent will be chasing it up constantly. At least, thats my experience of both diverting and operating out of MAD.
Its not as simple as you make out with your off the cuff comment. What time did you land? Was it busy? Fuel trucks have to do their routine pre booked scheduled aircraft before doing any extras (a no notice diversion is an extra - surely you dont expect the world to stop to accomodate it?). If you arrived at the 'wrong' time, you would of been at the back of the queue.
I'm sure you will realise, as most do, that the last thing anyone wants is a 35 Million pound aircraft stuck on the ground for no reason!
