Some signs

The first sign I wish to mention is one that I saw during my recent stay in Las Vegas (ugh). During a foolish attempt to move a foot or two, I naturally encountered a slot machine, which bore (roughly) the following warning on its side:

Warning: Nevada state law prohibits use of or loitering near slot machines by people under 21 years of age.

Ignoring the rather welcome fact that, for the first time in a long time, I believe a protestation that a certain restriction is "as required by law" as opposed to "a method of you-screwing permitted by law", I found this rather silly. Unlike the signs below, it says exactly what it means to say, but there's something amusing about the image of sinister 20-year-olds viciously loitering by slot machines. (As Woody Allen said in an essay on criminals, "He loitered for seven years, till he realised it was not the kind of crime that brought in any money.") The reason that there's no picture of this one is that, due undoubtedly to some kind of magical anti-photography coating, two attempted pictures, taken from a short distance, with a steady hand and adequate lighting, both came out so blurred as to be illegible.

This sign was on the door of a store somewhere near the University of Toronto -- I don't remember where exactly: This sign was in front of an elevator in Detroit Metro Airport:
