Cigarette flicking is a pet-peeve of mine. When I was younger, I worked at a motel and every morning I had to go around the parking lot sweeping up the butts and I was amazed/disgusted by how MANY there were, every day. THEN, I married a smoker who always flicked the butts out the window. One year we decided to take a camping vacation for a week in the VA mountains, so we hooked up the pop-up camper and headed down the road. She flicked a butt out the window, it lodged in the space where the top and bottom of the camper meet, ignited the canvas and mattress and burned the whole thing down. Total loss. So we saved what we could from the ashes and headed back home and as soon as we started down the highway, she lit up another cigarette. I have never wanted to choke someone so badly in all my life.
