You can see into three different states from the mountaintop restaurant's 'observation deck'. [=a platform built so that people can see or watch something]
We heard the captain shout “'All hands on deck'!” as waves crashed over the boat's bow.
“He seemed a little weird.” “Yeah, he's 'not playing with a full deck'.”
(..) So, what are you gonna do? We can be here all night. It's only one night. A boy may die. Well, why don't we just set up house here? Someone send for a pinochle deck and we'll just sweat the whole thing out right here. - I don't think he oughta joke about it. - What do you want me to do about it? (..)1957 12 Angry Men
