I get as angry as the rest of you, and am tempted to "leave a calling card", BUT if you do so at a lot where you park regularly, the next time you park there, the cretin will take revenge on you by deliberately vandalizing your car. From there, it's a downward slippery slope where no one wins.
The most effective response is to just park far away from where that guy parks.
When in a very crowded lot with few spaces available, and no "safe" ones (end spots, or wider than normal spots, etc), I try to park beside someone with a desirable sports or trophy car that shows no evidence of door dings or lack of concern. That maximizes the odds that the owner is one who will open his/her doors carefully, and who will also eneter and leave the space carefully.
