Not I. But I've noted on my commute (via the DC Metrorail), when the train stops between stations, the train operator will often say "stand clear" before it starts moving again. I've sometimes wondered to whom that is addressed—there's nobody outside in the tunnel and, even if there were, there isn't much space to "stand clear."
For some reason, this thread is reminding me of a book character from childhood. The teacher assigned the character a desk and said, "Sit here for the present." The character thought this meant, "If I sit here, I'll get a present." I don't remember what book that was, though. Simply too long ago.
