Of course theres leaving it under a bench I've seen it on shelves in aisles anyone who does that is grade A trash. Also leaving it on the side of a trash can annoys me to no end and in a urinal (you spit it in a toilet and flush it not on the side of a toilet either). My unwritten rules are when you throw away gum aim for the middle of the trash can not the side, I make sure its in a napkin or a water bottle or coffee cup. Seeing that crap just makes my skin crawl, and look at that person as scum.
