My first "real" flying job was with a small Beech 99/Twin Otter operator in West Virginia. The training department (no simulators in those days!) was run by some excellent individuals, one of whom is a Continental Airlines instructor today.
The airplanes operated from early morning to late night, making for an easy separation of pilot schedules into "Morning" and "Afternoon." The company chose to make schedules all one way or the other. Pilots were allowed to indicate their preferences.
It worked out that about half preferred early schedules, getting back home early in the afternoon, and the other half preferred to arise at a civilized hour,and didn't mind returning late. Pretty much everyone was happy with the rostering.
During one discussion of the compressed flying in the course of a day, some pilots complained that if they got behind (wx, etc.) early, they didn't even have time to eat, were hard pressed to "catch up," and discussed possible deleterious consequences of that. The chief pilot commiserated, and reminded the pilots that if they had no chance to eat, they were authorized to delay a flight for a reasonably short time to take some sustenance.
Sure enough,shortly thereafter one brash young captain flying an afternoon schedule arose early one morning, picked up his mail at the post office, did his laundry, reported for work just after noon, flew the first leg, then delayed the next flight to eat lunch! Fired summarily, he got his job back (with no union!) after a few days off, ending up years later as a captain at a US major.
Burp!
