Tip what you feel is best for the service you received, not whether or not you harvested. Also as to what is in your budget. We went on a hunt last year with a forum member, and I wished we could have afforded to tip the fella as he worked to get my wife her first deer, but it just wasnt in our budget at the time. We definitely plan to hunt with him in the future and he will receive a gracious tip. I would say 10% is the starting standard
I ordered a number one, with no condoms. My favorite nurse told me that it was on her. Everyone had a smile on their face.
