Tony is sending his construction/demolition waste to Barone Sanitation, but Phil discovers that it contains asbestos. At a meeting in New York he states that he will not accept any more unless he receives a 25% cut; Tony refuses.

He manages to tell Tony to call a taxi as he would not pass a drug test. Tony begins to call for help, but desists.
