LOL This reminded me of a story one of my buddies told me. He kept getting these guys anchoring right off his dock and they would stay for extended periods of time and were loud. He finally got sick of it, strolled down to the dock, dropped his drawers and went for a chunky dunk. Needless to say, he never saw them again.
This topic continues to come up on all the forums and will never be settled as long as there are brain dead anglers out their that just don't get it. Geez, maybe they just want to be your friend and don't know how to go about introducing themselves.
I personally move on, while being as noisy as possible.
