Teeny Weeny turn up with their 12 man bell tents, we're used to operating in the field we don't need plush tents, typical crabs etc.
Your recollection of the events suggests that Teeny Weeny had heated and lined tents available to them, but decided to show you how to do it man style? My recollection of such exercises is that if the AAC were fortunate enough to be able to find around half the tents they needed, they were doing well. They wouldn't even have known that liners and heaters were an option!
Nobody is criticising the RAF for having the right kit when needed - they're very good at that. More that in spite of this, they fight tooth and nail not to use it.
