So my daughter and I went out on the river with friends. Went to dinner then back to swim in the sunset. Coming in I noticed my holding tank was at 3/4 full. Got over to the pump out station and a boat was docked at the fuel / pump out dock. Same boat have been docking there for the past three nights. He always waits for the marina staff to leave then ties up and goes up to the micro brewery's tap room. When I came in I gave a long blast on the horns and then again when I was along side him. He and his teens came down the hill fussing and cussing. We advised him isn't something a boater should do, boaters are welcome to dock along the walls but never at the fuel dock. His answer was that there are no signage tell him not to dock there. We had some words with him after he called my daughter a bitch, as he left the dock I told my girl, see you really can't fix stupid
