I hate it when smokers throw their butts on the ground. I was walking behind a smoking dude today and he was right next to a trash can and opted to throw the remaining portion of his fag on the ground instead of in the waste receptacle.
Seems like smokers don't care about their trash. They'll just flick a butt anywhere. On the sidewalk or the grass, out their car window, out of a building's window, in the toilet... Have you ever done a beach cleanup? Notice how about half of the crap you pick up is related to cigs? Likewise check the HC courtyard. Every once in a while, there'll be a beer can or a bottle cap. Sometimes a napkin or a to-go box. But there's ALWAYS cigarette butts. Sometimes smokers dispose of their butts in other people's yards or in green spaces. They'll even do it if there's a trash can (one of the ones designed for cigs) within 5 feet!
Nasty, nasty smokers. You should be ashamed of yourselves. Not only are you paying good money to destroy your health and mine, but you display blatant disregard for cleanliness.
P.S. I appreciate those exceptions to the smoker rule...the ones who go out of their way not to litter. They have pocket ash trays or they use a bottle or can at a party to dispose of their butts instead of throwing them on the ground.
