I was always repulsed by the attitude of smokers throwing their cigarette butt on the ground thinking.....Somebody pick that up
Even worse were the smokers who would toss their butts into a urinal knowing that some poor bastard was going to have to fish that urine soaked butt out of the urinal
Not all smokers are that way...
I smoke. If I'm outside and there's not an ashtray around, I put it out and put it in my pocket or purse until I can throw it in a trash can. When I'm driving, I use the ashtray in my car, I have NEVER thrown one out the window. I have even been someplaces where I've seen people stomp their cig out on the ground and start to walk away and I come right out and tell them that's not where it goes. If they ignore me (which they will usually do!), I'll usually pick the damn thing up myself.
