Narrative:

I was driving along the road on our airport at ZZZ when a helicopter came across in front of me at about 5 ft AGL throwing debris up in the air. My first thought and my passenger said to me he has lost control and we got the impression from his movements he was in some kind of trouble or had lost control. The helicopter had departed the runway at about midfield where there are no exits or txwys just a grass berm and this is not a normal or; in my experience; a point of exit ever used before on this airfield. When I waited to see that he was in a controled hover and I pulled alongside the aircraft clear of his rotor and got out of my vehicle and gave a clear ground signal to the pilot to land his aircraft; he stuck his finger up at me and I repeated my instruction. He then moved over and then after repeating the finger action he departed the airport. I had made a note of his n-number. I then checked out on the FAA web site the owner of the aircraft. I then made a complaint to the FBO operation unit and they contacted the owners of this aircraft and made a complaint. The next thing that happened was I got asked by the police to make a statement as the pilot had complained about my action. All actions I made were in a normal ground crew manner and I only wanted to discuss with the pilot his movement across the roadway and to point out that all aircraft movement should be made in a standard manner used by all other users on this private airfield. I in no way interfered with his operation of the aircraft.
