Used to be a flight school at VKX. They're still around (initials are AA) that were a complete pain in the ass to the other airport users. First, they decided that they wanted their planes all parked together, so me and a couple of others got kicked out of our tie down space so they could have the ones up front. The instructors would regularly leave the plane at the pump between students (or while debriefing one I guess) which bogged things up when the place was busy. Then, despite being given prime parking with plenty of room to pull through, their yahoo flight instructor decided to swing wide and clipped a pristine O-2 sitting on the maintenance ramp.
