A male picnicker wearing glasses separates the women from the men and arranges each group alphabetically before stepping forward.

The picnicker wearing glasses diplomatically tries to discover why he and his friends have been stopped, and the leader eventually says this has all been a joke.

Everyone begins to eat before she notices she has sat at the wrong place, which prompts her and almost everyone else to switch to their assigned seats.

The host, annoyed by the commotion, asks Rudolf why there is not an empty chair if one of his guests is not there.

Rudolf is unable to forget about the missing guest and asks the host if he can go looking for the man.
