Bettina's Substitute, or There's No Fool Like an Old Fool.

Bettina was justified in being indignant because her employer, a married man, makes love to her. She tells her beau, Raymond, about it and he vows to get square with the old masher and teach him a lesson. He tells Bettina to send word to her boss that she is sick and obliged to remain at home for a few days, but she will send a substitute.
