My building has a problem with some lame-brain leaving cigarette butts in my garden, and in a small tree, in a planter near the entrance. Today, I was exasperated enough to make a flyer encouraging the litter bug to use a garbage can. My poster-rendering skills are fairly weak, but whatever.
Hey I pay taxes, I see the street sweepers...
Street sweepers have yet to collect trash out of potted trees on private property. At least on my block...
And, when I smoked, I'm sure I threw out a cigarette butt or two, in the street, but I never would be as bold as to put them in somebody's private garden.
