I agree with the general sentiments here. The hunter can of course budget tips for the hunt in advance on top of what the pro suggests, but he should be clear in his suggestions. I'd keep pestering your pro for some guidelines.

Sort-of related, but not exactly...you might find something in camp you might want as a souvenir of the trip. Make the owner an offer he can't refuse!,

On a day off once, I took a jaunt with an old-timer, one of the Zulu crew who had a notion where a bunch of vervet monks were and he wanted one for his own "pot" and I wanted one for kicks. I myself just plain love chasing monkeys!

We set off and spent the day searching for them and finally found a big troop that blew up and took off at high speed, we trying our hardest to keep up. I had my old Marlin 36 Sporting Carbine {alas, now gone...} and I got one on the wing so-to-speak.

We were just plain tuckered out but had such a grand time together. Saw a huge python and dodged a green mamba. My Zulu was nil, his English sketchy. My Afrikaans not-so-good, his fluent. So it was pretty much pidgin-this, pidgin-that the whole day.

Anyway, on the hike home we bumped into a fellow puttering along in his bakkie and we cheated a ride back to camp in the back. On the way, I offered the Zulu fellow a day and a half's wage for one of his knobkerries. He laughed and handed it over. Thought I was nuts no doubt! The cost was not much to me, but he appreciated it and I have one of the most memorable souveniers of any hunt I've been on. Used it on a coyote just last year!
