All of a sudden I am seeing Beer Cans with holes in the bottom. First I think it must be some kind of new drug thing, now I find out that is is called Shot-Gunning. which is a means of consuming a beverage, commonly beer, very quickly by punching a hole in the side of the can, near the bottom, placing the mouth over the hole, and pulling the tab to open the top. The beer quickly drains, and is quickly consumed. (wikipedia)
Just what we need, more drunks, getting high riding more scooters and leaving more trash.
