What when field circus runs long. When I was in, they always had a little game of seeing how close they could keep me out until it was time to work, so I would always arrive a few minutes late. Without those parasites, I am almost never late for work--not before, not since. (Aside from those times when random bad luck forces me to run late.)
And not by a few minutes, either. I would tell them that I needed to be in by a specific time, that would leave me plenty of time to get to work in time. But they would keep me out for one call after another. Or, they would deliberately leave late from boasting sessions so I would run late for work. Always finding one thing after another to keep them from leaving, often a good 20 minutes after everyone else was gone.
But you don't dare being late for a boasting session or field circus, for any reason.
