The subway sign below shows a passenger getting caught by the automated doors. The sign is mean to warn passengers not to get caught between the closing doors. The sign says the following:
It’s painful to get caught between the closing doors. Even more [painful] are the eyes of those looking at you.
In other words, it’s physically painful to get caught between closing doors at the subway. But, even worse, are the other passengers pointing their fingers at you because you were stupid enough to get caught between the closing doors.
That’s the overall message. It’s both descriptive and witty. But, would it help you avoid making this mistake?
I think the concensus is that the sign is witty, catches your attention, but ultimately it probably won’t prevent people from making this mistake.
What is interesting is the message about embarrassment and humiliation.
