Lot of good thoughts posted on this.
I think most guys want to be a good client, hunt well, and pitch in, and tip appropriately.
My though was that the nature of guided hunting is such that there often might not be much middle ground.

Most, or perhaps many, hunts probably allow a guy to cross one item off his lifetime bucket list. In the process probably share a very cool experience with the guide and would want to show gratitude for that.

On those unfortunate occasions where it goes the other way - leaky tent, lame horse, outfitters freeloading buddies along, confronting other outfitters or DIYers for an area, etc. then a customer may have strong feelings the opposite way.

Bagging an animal or not may very well be incidental to the service provided.
