The whole lights thing is a "courtesy manner" pilots should be considerate of others. There is competition everywhere but at the end of the day we are all on the same team. Another annoying issue is when pilots just randomly throw chocks on the ramp by an FBO instead of taking them back to where they belong. Sure its the ramp guy's job to put them back and clean up the ramp but sometimes they can't get to it right away. One day I saw 4 chocks just laying around at my home FBO and it was as if I was driving around cones. I asked the ramp guy about it and he was the only one working and was busy fueling up airlines.
