well - I don't get it at all: The way I see it - especially if there's a drift boat thrown in there, with shuttle cars and so forth, and the guy's time and (for some guides, not all) considerable experience and knowledge; $350 (sometimes for up to 2 anglers) is not a whole lot of money for a day's fishing. Either these guys are doing it for occasional fun, or for tips. If there is an expectation for tips - I for one - am not offended by the snarky request in the form of "make sure you tip your guide" remarks on some websites, and even advertisements and preparation lists for trips. What I am offended by, is calling it a tip in the first place. A tip is not for "good" service, and is not "customary", or "expected". It is for exceptional service, and it is entirely discretionary. So what's exceptional? that's up to you to decide, not this forum. But one example is telling. Another website had a guide participate - who - in addition to boasting about the number of fish he always catches and hawking for clients, remarked about the insistence of a client wanting to do only dry-fly fishing on this home river of his. He proclaimed his dismay about this - apparently not familiar with anything other than soaking san juan worms and prince nymphs, ergo, unfamiliar with jack. Yet many client's don't know jack either, so they wouldn't know the difference and would shower this guy with tips. This "always" tip thing is a US custom that contorts the meaning of the term - if guides undercharge with an expectation of a tip, it is basically amounts to them working as a volunteer, for fun, or at a loss - and you are simply being made to feel guilty.
