All these parking stories reminded me of one from a few years back.
I was at a convention that never had enough parking at the hotel, so finding a spot was tough. As I drove up, a woman came out of the door of the hotel and was walking towards her car. I rolled down the window to see if she was leaving, but she didn't hear me as she didn't answer my question, just hopped into a car. I hear the car immediately start, so I figured I was in luck and could take her parking spot. But she didn't move. At the moment, no one was behind me, so I decided just to wait and see. She still didn't move, and finally someone did drive up behind me so I couldn't block the lane anymore. I started forward, and another group came out, saw me, and told me they were leaving if I wanted their spot. It was about 3 spots forward from the not leaving woman. As they backed up, so did she!
I was directly behind her spot at this point with no where to move. The leaving car prevented me from moving forward and there was a car behind me. I honked and honked and waved my hand out my open window, but she wasn't stopping. She did stop just before plowing into the side of my car. She pulled back into her space. I took the space of the other group and the car behind me got this woman's space.
I just couldn't believe that she would back up without looking. This covention was always packed with people of all ages and there could well have been people walking through the parking lot. Not to mention cars driving past.
