Not strictly true ...

Just as I stepped out of the lift I noticed the sign so, unfortunately, did not have a chance to snap a picture. The sign in question said, "Information is not available from this help point at present." However, the information I got from the sign was that the help point was broken, which would have been a clearer message, "Sorry, this help point is broken."
