As an ex-guide in The Louisana Marsh, here are a few of mine:

Don't expect that your guided trip will be the best day of fishing in your life, just because you paid for it. Your guide wants to put you in to a ton of fish, as badly as you.

Don't be late. It can make the difference between getting to a great spot in time, or watching others enjoy the fun.

Don't be afraid to ask if there is anything you can do to help out. I could make a big difference in the results of your trip.

No freakin bananas

Don't assume the guide is your slave. He/She is there to help you have a great fishing experience.

Don't base your tip on the amount of fish you catch, but rather how hard your guide works to make your trip a good one. If you catch a bunch of fish, then toss in a few extra bucks

Don't ask other boats how they are doing. Your guide is fully capable of figuring that out all by themselves.

Do ask if there is anyhting you need to bring (i.e. suncscreen, lunch, pop, raingear). You would be suprosed how many people show up without raingear. I've had many a wet rides home, while my client wore my rain gear.

Do ask where to get a liscense. Some guides actually can issue them on board. Most don't

Do ask how long you will be out on the water. Some people (diehards) will want to fish daylight to dark. Others will be more than happy with 5 or 6 hours on the water.

Do go on your trip with the intention of learning some new techniques, and sharing a good day on the water. Like I always say, "The fishing is always great, sometimes the catching is slow".
