Business Is Business (film)

Greet roleplays the customers' sexual fantasies. These incidents are recounted in the form of anecdotes throughout the film. The roleplaying involves Greet being a wicked witch, a schoolteacher, a feathered chicken, a corpse, a woman commanding her cleaner, and a surgeon. Sometimes Nel assists her by playing a part in the roleplaying.

Nel lives with Sjaak (Jules Hamel), a guy who likes fishing and who lives on Nel's money. Nel and Sjaak are continuously fighting. Greet convinces Nel to respond to a personal ad. The following blind date in a restaurant ends up in throwing cakes. Nel wants to clean her dress and then she meets Bob (Bernhard Droog) and they fall in love. In another fight Sjaak almost kills Nel with a knife, and Nel decides to move in with Bob in Eindhoven. Bob turns out to be boring, and Nel visits Greet in Amsterdam. Nel no longer wishes to work as a prostitute, and she turns out to be pregnant. Nel and Bob marry in Amsterdam, and all of Nel's former colleagues pretend that she worked as a seamstress.

Greet meets a married man, Piet (Piet Römer), in the bar where she hangs out. He takes her to a striptease club, and afterward they have sex at her house. Unlike the other men, he doesn't have to pay. Piet brings Greet a bouquet of red roses. The next time they meet, they create a romantic atmosphere and he stays overnight with her. Later, he takes her to a classical concert. She dislikes it and makes a scene in the concert hall. When Piet finds out his wife is pregnant he stops seeing Greet. At the end of the film they meet again, and Greet says he should name his child "Greet" if it is a girl.

The film ends when Greet makes the customer that plays the cleaner clean up Nel's marriage party.
