You're going to get complaints like that when you have people living at the airport and some people think they own the place (in some ways they do).
I was there and a local saw a mate land in his aircraft and he insisted that his landing was too hard and told him he had prop struck. There was no damage to the prop and the landing wasn't overly hard. The local then researched and found the owner of the aircraft, rang him up and told him about the incident that never actually happened. Strange bunch. Overalls man is another story again!
