Had a mate at Strubby in the '50s, perpetual Fg Off as he couldn't pass "B". When at last he was "deemed" to have passed, and got his Flt Lt; first thing Vin did was to tell his wife to go out and buy a pound of steak - in place of the egg 'n chips on which the family had had to live for so long !
Even as Flt Lt, we survived for years only by grace & favour of kindly Bank Managers (where have they all gone ?)
