When you have spent 3 years at uni whooping it up with the other young and beautifuls, then passed 'Cranners' with flying colours, don't go into dinner on day 1 of your hold at a big unit and ask the Pilot Officer (in refined tones) "What are you holding for then?"
That might just make the 2 x Flt Lts at the end of the table almost choke on their dinner, remind the fresh Fg Off that non-graduates also joined the RAF, the said Plt Off had been there for a couple of years and they had also had the honour of being SPOs etc etc etc. Sustained banter. Chips on shoulders, but oh so beautifully balanced. They (sort of) looked after me.
