Benjy demanded that Howard change his tone: "Don't take your anger out on me and talk to me like that...talk to me respectfully."
Howard refused: "Don't bring my guests into your bullshit...I started out respectfully. Now I'm getting annoyed."
Benjy continued to rant ("Don't act like I did something to use you!") but Howard stopped him, asking him to act professionally: "We're conducting a business."
