Adam Bock’s The Receptionist is a slippery workplace comedy that starts with a seemingly innocuous monologue by an unidentified male about his love of fishing, then shifts to the workers in an office, where a Mr. Raymond (the monologuist), is unexpectedly late. Amid exchanges of personal gossip, the receptionist Beverly (Katie Finneran) and a supervisor, Lorraine (Mallori Johnson), receive a visitor from the “home office,” Martin Dart (Will Pullen), as they await Mr. Raymond’s return. Director Sarah Benson’s revival of Bock’s masterly piece sustains a sense of inconsequentiality, even as discordant notes pop up, until the piece reveals itself as a chilling paradigm of what Hannah Arendt, in covering the trial of Adolf Eichmann in 1963, called “the banality of evil.”
