Last Saturday I happened to stop by my office to pick up something. As I was leaving, there was a car parked in my lot while the driver went to the store next door. Susan and I saw the passenger door open and the ash tray dumped into my lot.
I pulled in and blocked the car, and in a remarkably calm (for me) manner asked the passenger if he'd kindly pick up the butts. He ignored me, rolled up the window and locked the door.
I called 911 (police station is in next block). As one responding officer said, as I remarked on three cars showing up, 'it's been a slow day and we were about to fall asleep'.
Yes, the butts got cleaned up. No, I didn't press charges because of the inconvenience to the legal system if I did -- they'd have to bring in an out of town judge to hear the case and litterbugs just aren't worth that.
Litterbugs aren't worth much else in my opinion.
