My father was a high school director. It was a 900-student school for lowerclass jobs, with... well, many lowerclass situations with students who hadn't necessarily ever touched a phone, in the 80s. Part of the job was managing financial resources and deciding of his own salary. He decided to lower it, because he didn't feel like he needed that much. And he decided to apply it retroactively upon two years. He gave money back to his school. I wonder whether I'm plain selfish for thinking he would have had better credit taking the money (even to give it to charities) than returning money to a public institution. But I find the gesture admirable.
