I always try to tip restaurant servers and other service employees generously if the service warranted it. I was always told you don't tip the owner of a business, his charges should included what he expects to make for providing a good or service, which makes sense to me.
On party (or head) boats I always tipped the deck hands that helped with bait and equipment.
But, a guide is a one man show and I would think his charges included what he needed and expected for the service he provided. He has an investment in boat, motor, insurance, etc. If it were me, my charges would be based on what I needed to cover cost and make a profit for myself. I've had guides work their tail off and the fish simply were not biting. I did not expect a refund not do I feel a need to tip if we load the boat.
What are others thoughts on this?
