How does Edward Albee use imagery in A Delicate Balance: A Play?

THe imagery is consistent with the setting. The entire play takes place in one room, "the living room of a large and well-appointed suburban house." In that room is a bar, which is well stocked with bottles of liquor. Time changes from Friday night to Saturday evening, then later the same Saturday, and eventually to early Sunday morning, but the setting remains the same. This one room is the focal point of the house, where all the characters can meet to argue about the living arrangements in the other rooms of the house.
