The famous story at UAL comes to mind. Captain and FO are at a ball game. Having a good time with just a couple of beers. They finish and it's just after 12 hours prior to takeoff (back before we were at 8 hours). FO saying nothing to Captain about the fact that he finished his beer at 11:58 prior to push, but she decides to call the FODM and report him. Stay classy!!!!! There are easier ways to move up a number
