First time in Germany (November 1976-July 1979) I was riding the train and was just checking out small towns neighboring Frankfort and happened upon this diner when I got hungry. When trying to order and not yet speaking German, the waitress was struggling taking my order. After a couple of minutes she left and came back with the owner who spoke pretty good English. After taking my order he sat down with me and told me my meal was free. Apparently, he had been a prisoner of war in WWII and told me he had much respect for Americans because he was treated much better as our prisoner than he was by the leaders of his unit. Told me anytime I came back the meals and drinks were free for me. Went back a few times a week over the years over there to talk to him and thank him for his hospitality but, did not want to take advantage of him.
