What does maurice do when holden refuses to pay him the additional five dollars?

Well at first he refused to pay her more, and she leaves in a huff.

but then she came back with company (aka sunny) to collect her money he refuses again

so "Maurice pins him against a wall while Sunny takes the money from his wallet. Maurice snaps his finger into Holden’s groin, and Holden starts to insult him in response. Maurice slugs Holden in the stomach and leaves him crumpled on the floor."

Hope that helppss :]

she is later raised by him and his wife, madame valmonde, who sees her as gift from god, as the couple cannot have their own children. later, desiree falls in love with a wealthy man, armand aubigny, and they get married.
