Street Food

Why do people dump their old food on the street "for the birds"?? Or for pigeons, rats, roaches and god knows whatever other kind of vermin. Drives me crazy when I see a big heap of moldy bagels sitting on the sidewalk. Soooooo gross. Seriously, in what world is this a good idea?

Exhibit A from the corner of Howard and Broadway this AM. (Yeah, now who's crazy--I know I know....)
