When Gus enters the room through the right-hand door—the door the target is supposed to walk through—he reveals himself to be the target. It’s left ambiguous whether Ben has known this to be the case the entire time, or whether he’s only learning about it now. Either way, that Ben must now betray his partner illustrates how exploitative working conditions and hierarchies pit workers against each other. The play’s closing scene also sheds new light on the play’s title, revealing that Ben and Gus have both been “dumb waiters” all along. Gus has dumbly waited around for hours, utterly ignorant of the fact that he has a target on his back. Meanwhile, Ben has been a “dumb” (as in mute) waiter too: he has spent the entirety of the play waiting for his boss to tell him what to do, unwilling to speak out against his higher-ups and question his exploitative working conditions. Up to this point, Ben has blindly obeyed authority, seeming to believe that doing so will present him with the opportunity to improve his social standing and quality of life. This final scene shows the grave consequences of Ben’s unquestioning obedience—it has incentivized him to betray his partner. Not only this, but it's not even clear if killing Gus will improve Ben’s standing at all, or if he’ll continue to be exploited and undermined by more powerful forces who know that his lower-class status leaves him with no choice but to do as they say, even if that means harming himself and others. Finally, that both Gus, the rebel nonconformist, and Ben, the obedient follower, should meet such grim fates reinforces the play’s underlying position that life is absurd and meaningless. People are doomed to fail, regardless of whether they think for themselves or seek reassurance in upholding the status quo.
