Food on a SSN

Back during our 1967 WESTPAC deployment we ran very low on toilet paper. I asked the chief to give me "extra military instruction"  and have the cook tell me to clean out the walk-in chill box. In those days, possibly still, apples were packed in corrugated boxes but they were individually wrapped in squares of soft blue paper. Knowing this, I carefully unwrapped all the apples, ... and because it was supposed to be punishment,  I cleaned the rest of the chill box. Enroute to the fantail to dump all the trash, one box of blue paper went to the radio shack, and the radiomen had toilet paper when the rest of the crew worried.
