Early 80s and having a great time as a first tourist on shiny 10 squadron. Very experienced Flt Sgt ALM is looking after a cabin full of army pax, headed by a Colonel who obviously thinks he is a VIP. Colonel sees Flt Sgts rank insignia and interprets it as a Staff Sergeant and tries to get a drink.
As the ALM walks down the cabin, past the Colonel
Colonel "I say, Staff, Coffee white one sugar please."
ALM ignores Colonel turns around and as he walks past Colonel again
Colonel "I say Staff, Coffee white one sugar please."
This continues several times, each time the ALM ignoring the Colonel.
Finally, as the ALM is ignoring Colonel for about the fifth time the Colonel gently grabs the ALMs sleeve and says
"I say Staff, Coffee white one sugar please.
ALM "I am not a Staff Segeant Sir, I am a Flight Sergeant."
Colonel. " Oh I say, If you were in the Army you would be a Staff Sergeant."
ALM. "Sir, If I was in the Army I would be a fcuking General."
