When NCO aircrew allowances were dropped to 75% of the officer rate, a Herc crew took the Station Commander flying. The predictable S1 boxes were handed out, then there was an explosion of outrage from the Stn Cdr "Someone has already eaten some of this!".
But in fact every item had been trimmed to 75% of the normal size! "Sorry Sir", said the ALM, "That's an NCO's box!".
Point made and IIRC, things soon returned to normal!
