So, a client that I took fishing last year, contacted me via email and said that he felt bad because he had not tipped me. He said that he found out recently that it was customary to tip a guide if he learned from the guide. He went on to tell me that his nymphing skills had been greatly improved and that he bought a copy of my book and had found a lot of fantastic places to fish. He was offering to send me a tip in the mail. While I was very appreciative of that, I told him that it was unnecessary and that it was rewarding enough for me to know that he had improved his fishing and benefited somehow from my book. I usually to get tipped. I have had clients double my fee as a tip after having excellent days of fishing. This does not always happen however people should realize that guides work very hard and even if you don't catch fish, you are still walking away with years of knowledge that the guide has just instilled in you. That knowledge will help you to catch fish in the future.
