Ok, let me start by making it clear that I absolutely hate, hate, HATE shopping and malls and crowds and that whole scene in general. I much prefer doing my shopping online, but sometimes you just have no choice but to go out into the real world...
And what happens many times, as if shopping itself isn't unpleasant enough, I'll get back to my car in the lot and see that the genius who parked in the spot next to me has left about 5-6 inches between his car and mine. With a car like mine (2-door coupe), the doors are really long and you need a lot of space to swing them open far enough to get in the car. Sometimes I can barely squeeze into my car when these clowns are leaving me so little space to open my door.
And sometimes it's not even the other guy's fault. Many times I've been in lots where the guy next to me was perfectly fine, parked perfectly well in between his lines, and there was still not enough room for me to open my car door. I'm pretty sure that store and mall owners are making the parking spaces narrower, by painting the lines closer together than they used to, just to cram in the most number of cars possible.
