The Ship's Provisions
A captain provisioned for a two-week voyage.
"Add a week's extra," his first mate suggested.
"The voyage is two weeks. I won't pay for provisions we won't eat."
The voyage took four weeks. Storms, becalmed days, a broken mast.
The crew survived by rationing. Barely.
The captain's next voyage was provisioned for five weeks. It took two. He didn't complain about the extra.
