I got a lot of complaints about a lady who I think was running the Flight Line in Vintage most of the time. I personally heard her be very rude to people for no reason. At times, it seemed nobody working the Flight Line could do anything right.
She yelled at one guy, "Are you just going to leave your landing light on all day?" He smiled and asked what difference it made to her! Now if she'd said, "Your master is still on", it might have gone over better.
At one point she came off the line on her scooter and you could tell she was mad. She started yelling at people who had tents out past the tail of their airplanes. She asked them if they understood that they didn't want to turn any planes away and they were parking planes at the ends of the rows as the OP mentioned. That's okay, except in this case, it was on one of the few rows in Vintage where the airplanes were tail to tail. I waited until she was alone and walked over and thanked her for the hard work she was doing. When she smiled, I pointed out that there was no room to get a plane down this row anyway. She gave me a look, shook her head, and rode off!
