I have a less dramatic but similar story. In Portland OR, there is a lot of Asians (ie, non-American born) and during a conference, we went out to lunch, and we saw a group of Asians, very nice clothes, gold watches, get in to a Lexus and just leave all their lunch (takeout) bags in the gutter. Their cups, straws everything. Just set it down and drove off. This was in the mid 90s, we were all pretty shocked. But I have since learned, that is what is common in Asian countries, just set your garbage down wherever you want. I even read a blog article where a dev when to a tech convention in some large Asian city, and there were no trash cans anywhere, and that the only place to put garbage was on the ground, and there were people paid to pick it up.
