Candy Davis as Miss Belfridge does a delightful homage to Marilyn Monroe by re-enacting the subway scene from The Seven Year Itch (1955).
In the last scene as the staff give the Japanese men the "British Workers' Salute," Mrs. Slocombe inadvertently knocks a hat off the display. Miss Brahms looks down as it hits the floor, and it stays there at the end.
This would appear to be the only episode in which we get to hear the staff's Christian names.
