Sensible Sign

Posted outside Carlos' n Charlie's Famoso Mexican Grill and Fiesta in the Flamingo Hotel & Casino in Las Vegas is this sign board.

Nothing really interesting about it ... except for the one in the lower left. I had to stop and think for a moment after I saw it.

Very appropriate. No admission, but if you don't pay to get out, you'll be stuck at the bar until you do.

And that might not be too bad an idea. Waiter! Hold the check!
