Yet another sign that people don't really differ all that much. American truck drivers are famous for pissing just about anywhere, and are notorious for tossing out bottles of piss with little or no regard for others. Here is a sign located at the container terminal belonging to the Evergreen shipping company at Tokyo's Aomi Wharf.
The sign is along the edge of a very large truck waiting area and basically says that anyone caught pissing in the trash can will be barred from the premises.
Just think, this was enough of an issue that they had to go to the trouble and expense of putting up a sign.
