Manfred and his 89-year-old father do not spare any punches. Since his stroke, the former chef of a service station is constantly close to tears, while his son is finally free to undertake the great renovation. Early on, old Lenz laments: “This is the end.” But dying is out of the question. Nobody will be left in the lurch. Pig’s head, liver dumpling soup and pale ale from the bottle hold body, mind and the shop together. With his portrait of the service station “B12” between Munich and Passau and its elderly regulars, Christian Lerch has made a slightly different documentary film. He shows Bavaria as if from a sketch of Karl Valentin: rough, anarchic, with a beer-infused depth.
