So ein Millionär hat's schwer (1958)

Edward Collins wants nothing more than to live a modest life. But as a millionaire with a luxurious villa, chauffeur, and everything his heart desires, women are desperately after him. This time, however, Edward wants to play it safe and, together with his devoted butler, Alfons Heinz Erhardt, hatches a plan. The sweet waitress Ninette Germaine Damar, whom he meets by chance, tells Edward that he is completely penniless. Ninette promptly gets him a temporary job as a parking attendant. But that's only when the complications really begin.
