I'm one of those that park out in no-man's-land as well.
The most door dings I ever got was when I started parking in the "faculty" parking lot at college where I work. It only took me a few weeks to learn to park somewhere else.
My door ding incident I posted last year:
I parked at my local NAPA and as my wife and I were leaving the store, a car was pulling in to park next to my truck. The car was your typical "westside special" and so were the "occupants." You guys know the type, with their underwear showing and no shirts, loud music, rotten looking car, etc. I hear BAM and look up to see the passenger getting out of the car with the car door firmly pressed upon my side door. He just looks at me and says WHAT? then walks inside, along with the driver.
Well, I had to consider several things. One, my wife was with me and she doesn't need to see me get "fresh" with the local thugs. Two, with as much as I love the fact my vehicles have very few dents, scratches, and excellent paint, I would need to calm myself to the point of NOT maiming or setting them afire, etc.
So my wife and I got into our vehicle. We had been to lunch earlier and I had a 64 oz Coke/Pepsi product sitting in the cup holder. I start up the truck, roll the window down, and remove the lid. Just about the time these guys decided to start coming out the door, I simply tossed the drink through their open window, watching the contents go splashing about through their interior. As I rolled off slowly, I looked at the guy and said WHAT?
