How does D. L. Coburn use imagery in The Gin Game?

Imagery:

"That's why Magicians like to play old age homes. Half the audience is shaking so goddamn bad they can't focus, and the other half's asleep." Act I, Scene I, p. 18.

"Don't kid yourself that this is anything more than a warehouse for the intellectually and emotionally dead." Act II, Scene 1, p. 36.
