Aw ditor,
I'm impressed, nay, totally and overwhelmingly in awe that not only could you sell nothing to someone else, but you actually persuaded a customer to part with money for nothing in return.
Perhaps a different 'ullage' to the one us stackers were used to. Ours was the empty headspace above the liquid in the fuel tanks - also used as a nickname for a certain OC POL at a large AT base in the early seventies.
