This isn't a news story, but something I actually witnessed.
I went out to lunch at a local burrito place and brought it back to my car to leave. I was fiddling with the radio when a fellow patron brings out a bunch of napkins to his car. Apparently, he had dropped his drink all over his open car door. I watch as he calmly uses one napkin after another: wipe, wipe, throw on the ground next to the car; repeat. I was stunned and watched him go through about 15 napkins like this, throw the rest of the clean napkins on the ground, get in his car and drive off. I thought about saying something to him, but I think it would have just led to confrontation and I'm scared of that with strangers.
