I'm just back from Chicago Midway airport, and I almost went insane while waiting for a friend's flight to land, because every five seconds (I counted) there's an announcement saying, "Caution! The moving walkway is ending." (Anyone too dumb to figure out when the moving walkway is ending might just deserve what he gets.) I generally am so happy to be walking while in an airport--versus waiting in a line or being sitting cramped on a plane--that I tend to skip the walkways, unless I can't see where it ends, and then I figure it's probably a good idea to get onboard. But what really cracks me up--and I saw this at Midway--is when a walkway isn't moving, and yet people still walk on it. What are we, sheep?
