Tony was a cruel master indeed. And to get to be called "Master" all the time. Man, that hardly ever happens to me. I think Major Healey would have been nicer to Jeannie. But I don't know for sure if he liked girls.
Now Roger got plenty of girls and yet always wanted Jeanie (I think to get more girls). If I had been Roger, I would maybe have loosened a few bolts on the centrifuge when Tony was doing G-force training.
