Arabian Nights (1979)

Karin, manager of a gas station, has been in a terrible mood for some time. Its turnover has been declining since the sharp increase in the price of gasoline. To make matters worse, his friend Wolfgang regularly uses the car to satisfy his passion: motor racing. One day, Karin discovers that Wolfgang is cheating on her with the lovely Christl. Never mind: Karin decides to leave for London with Christl, to find an oil magnate there.
