The only thing that seems a bit off to me is that he doesn't give you 50 minutes when he is late. The other things seem to me to be the dynamics between you and him which is probably dictated by you by being a "good" client. Probably he would be more outgoing also with you if you would indicate yourself that this is something you would want. Without you indicating that he would just perhaps overstep your boundaries and that would not be good either.

Why do you think you need to be a good client anyway? You are not paying to him for his time and not for being "good". It is very likely that he doesn't expect you to be "good" and you are hurting yourself by trying to be that for no good reason. It seems to me an important topic to explore.
