So when you go to a restaurant and pay for your meal you don't tip you waiter? Most of these hunts the prices go to the outfitters not the guides. If the outfitter is the one who is guiding you that is one thing but if there is a separate guide that is busting his butt to get you an animal a tip is greatly appreciated. I have guided in the past where I've been a glorified taxi service -- taking hunters to and from stands, setting up stands or blinds, carrying gear, delivering lunch, game retrieval/skinning/caping, and general go-fer.....by no means taking a guy on a pack in trip. The hunt was a $4k rifle hunt, I was tipped $100 each by a couple guys and nothing by others. The money was very appreciated, but I also understood the guys who didn't tip. Not all of us have a ton of money to throw around, I've been on hunts where I've tipped almost 20%, and others where I don't think they deserved anything so they didn't get anything. Just do whatever you think is fair for the service you got, good luck on you hunt!!
