Plot
Moss and Aaronow are heard plotting to steal the leads from Williamson's office. Ironically, it's Levene who gets to them first in order to get the sales he desperately needs.
Levene and Williamson
Williamson is the office manager and effectively hands out the sales leads to the men. Ironically, he withholds them from Levene because he doesn't like him. The way he's spoken down to him the entire time he's worked there causes him to ensure that he won't get the leads and thus will lose his job from not making sales.
Lingk
Lingk decides to write a check to Roma in order to close a deal with the manipulative salesman. He feels he's just made a step in claiming his power back in the world. Ironically, he comes into the sales office later to ask for his check back. His wife won't allow him to purchase the real estate. And he even feels bad for asking Roma for the check back as well.
Mitch and Murray
Mitch and Murray are never seen throughout the play. They are the owners of the sales agency. Ironically, it is their presence that cuts through the men as these bosses make such high demands, while threatening to fire low producers, that the men are constantly on edge to sell or lose it all.
The Sell
Every one of the men working for Mitch and Murray desire to make a living, to be number one, to provide for their families. They want to be the best. Ironically, these sales contests that they are put into bring out the absolute worst in them. They are caused to compete with one another to the point that they don't even like each other, and most of them don't even like themselves for what they must go through and do in order to even keep their jobs.
