I was on the aircraft carrier Nassau during World War II. It was a smaller carrier, called a jeep carrier. On a ship of 900 men there were no barbers. No one volunteered.
Our executive officer made a rule: anyone put on report for a wrongdoing would have to be the ship's barber for a month. Each month's barber had a different version of what a haircut should be. They were even ruining my butch haircut.
The sailors could hardly wait to go ashore to get a decent haircut. . . among other things.
