The grocery store near my house has a very small parking lot underneath the store. It is only large enough for about 12 cars. Most people who go to this grocery store go on foot, as it's in a very dense neighborhood, but I tend to drive because I live up a steep hill from the store. Often all the parking spots are full, and what you can do is sit in your car near the entrance (which doesn't hinder anyone from leaving). One time I went to this store and waited in my car until someone left, and I pulled into their spot. Someone arrived just after me who didn't feel like waiting for a spot to open up, and he impatiently pulled his car into a space which looks like it could be a parking spot but is marked off as "DO NOT PARK HERE" and has diagonal lines painted all across it, so it's clearly not a parking spot. (Please forgive me if my description doesn't make it clear here). He was parked at right angles to my car. My car was in the very last of a few legal spots on the right back of the store, and his was illegally parked on the back wall. The car in the first legal spot on that back wall could easily pull out without hitting my car, but it was clear that it would be very difficult for him to pull out without hitting my car. It's easier to drive forwards than reverse, so you could wriggle into that space, but only a superior driver would wriggle out harmlessly.
I felt really sick that day, so I sent my daughter upstairs with some money to pick up a few things, and I waited in the car miserably. The man who'd pulled in impatiently just after me came over to my car and gestured at me imperiously. Then he informed me that I needed to move my car because he wouldn't be able to get his out. There was no "please" or any other kind , polite language, just a flat out demand. Mind you, he hadn't gone into the grocery store yet.
I told him, "No, I'm not moving my car until I am ready to leave." From my point of view, I was legally parked, he was too impatient to wait for a proper spot, and also who knew if I'd be there when he was ready to leave. I also had no other spot to move to, and on top of that, I was sick.
The fellow was really peeved that I didn't hop to and tossed his head around and then demanded to know what I was doing there in my car. Here I am ashamed of how I reacted: I should have just given him an incredulous stare, told him it wasn't his concern, or used any of the appropriate shutting-down remarks. But I was sick and miserable, so I actually told him I was waiting for my daughter. Of course he felt that was inappropriate. At this point I rolled up my window and firmly averted my gaze from him. Eventually he gave up and went into the store (possibly to complain about me?
). My daughter came out with our groceries, and I left without seeing him again. Odds are someone else came in and took my same spot, though. I would hope he learned something about using the marked, appropriate parking spots, but eh, probably not.
