Put something UP

I was traveling some years ago and passed a Holiday Inn with an unusual sign. It interest me and I ended up looping around and ate at the restaurant inside. When the young lady came to wait on me I ask her about the sign. She said, she did it because "The boss said to put something up!". That is exactly what the sign on the marque said "The boss said to put something up!"...true story, Bessemer, Al USA!
