I took this picture in the in-store McDonald's at Wal-Mart. I don't know which is more WTF; the fact that some people are so cheap that they would try to fill a bag of ice from the McDonald's ice machine inside a Wal-Mart (how much is a bag of ice at Wal-Mart? $1?), or that this is apparently such a common phenomenon that they had a permanent plastic sign manufactured specifically for this situation.
