Never had that happen to me with a guide, but have heard of it happening. Always thought it was foolish on their part, someone that's on the water daily and probably has a good feel for what's happing at any given time.
Seeing as how he thinks it's just fine to jump someone I would let everyone know he does. If you want to find fish just find Moron the Guide and cozy on up, he's OK with it. Does it all the time. If he's employed by an outfitter call them and tell them what you plan to do and ask how they feel about it. Do all their guides feel the same way.
Got a board the locals read?
