Out of Work Sign

I found a sign on a non functioning door at the Plaza las America's mall which made me chuckle.  It's an example of how someone should check with a native speaker when trying to translate Spanish into English.  I understand in Spanish this sign says the door is out of service.  In English I'm led to believe the door is out of work and looking for a job...  I guess even doors need a hand once in a while.

I remember when we started putting for rent signs at some of our homes and instead of correctly putting "se renta" (for rent) I accidentally put "en renta" which is bad Spanish.  Perhaps I should start taking my own advice!
