A little bit different than what you are talking about is a shady deal that goes on here in Idaho. In order to be a guide on a river you have to have a permit. There are only so many for each river. Some rivers do not allow guiding at all. But say a fly shop owner was to take a couple guys to this restricted river for a "fly fishing lesson"... That just happened to last all day and cost around 400 bucks, snacks included of course !!! happens all the time.
