I'm sure Brett doesn't really need anyone defending him and my only experience with him is one guide trip with my daughter (she's the one holding the "Fish of the Week" on his website...guess that doesn't get updated as much as the fishing report), but I wouldn't be so quick to judge by one off-hand comment in a fishing report. When he took us out, he did exactly what we wanted -- put us on a lot of fish, answered all our questions, and taught us a couple things. It was the first time either of us had a fly rod in our hand, so he definitely earned his guide fee and we had a great time.
As for the slob comment, I don't think he was implying that everyone out there that isn't on the water by 6:00 is a slob. However, on any given day I'm pretty sure you can find a couple that fit that description on the water -- especially as it gets busy later in the day. Write a fishing report (or anything) hundreds of times and you are bound to (1) offend someone or (2) write a very dry report.
