Arschkalt(2011)

Rainer Berg is a frozen food delivery man who has been let down by life. He has withdrawn from the world in order to avoid emotional trauma. His outlook on life is shaken when he is assigned a new colleague, ex-hairdresser Moerer, who turns out to be a pain in the neck. "This van is too small for two!" But it's no use, Berg can only get rid of his annoying co-driver once he has turned him into a good salesman, according to the new boss. Team spirit is suddenly required from the cold-ass misanthrope Berg.
