I think this manager didn't care about you being late or not. All he cared about was results. If you would have come in at 9:15 AND showed poor results and then came up with an excuse he would have punished you for it. But if you came in, with a confident smile on your face because life was good and you loved your work, he would have just smiled back at you.
If work hours or company policies are not posted, couldn't you also say that expectations aren't made clear and communication is lacking? Aren't some sort of standards still needed? Otherwise everyone would cram everything into a 4 day workweek and be MIA on the 5th day.
That's not the impression I get, with the little book and all. It's no different to the managers who walk around with hand puppets that fulfil the 'bad cop' part of his routine.
