Jumpseater,
If I was incorrect in my assertion, I am more than happy to take the rap in public, call myself names, be embarrassed by my lack of knowledge and apologise to anyone and everyone I have offended.
I also put forward this example of why it may be better to state 'operational reasons' than give a specific reason.
I am slightly familiar with cold soaked fuel, however never considered it in this instance as the aircraft had been flying short sectors and on the previous sector the departure point was at +12.
My son did not pass on my thoughts to other passengers, as we only discussed it once he had landed.
