sounds to me like you fulfilled your commitment the first hunt, then went out of your way to appease him the second go round. in my view, a fair minded person with character would have paid the daily fees for the first hunt.
his displeasure, even after you explained "it's either a young male or mature female", and the circumstances of the hunt, is unfounded.
some people just expect something for nothing these days!

hope you get the balance due!
