So is the “inspector” an employee of the DNR or other conservation agency or is he just out there as a volunteer on his own? By no means should an angler lose his temper and run over a chair, but you really should not be out there trying to enforce or remind people of state law if you are not supposed to be. Maybe they are part of the lake association or something. I know a few lake associations around here have received authorization from the DNR to remind people about this at the access.
Way back in the mid 2000’s, I was a surveyor for the DNR at Mille Lacs and then again one season on three smaller lakes near Aitkin. I wore a uniform and some people were a little hesitant to answer the questions I had, but once I told them I was not a CO and only trying to gather information about the lakes, they almost always cooperated. A couple times people did have illegal fish and I asked them to return them to the water, which they did not. A quick speed dial to the local CO took care of that.
I can recall three specific times when the anglers flat out refused to talk to me or answer any questions. I simply stated that was their choice and told them to have a nice day. I then called the CO and informed him of this. Usually when people completely avoided me, they were hiding something.
