I showed him my air itinerary. After he heard I entered via CDG, he had that look of disgust on his face, like those inefficient French. Also, from my past stamps, he could see that I made multiple trips to/through FRA previously, of 1-2 week duration. He let me go with a strong warning to be sure to get the stamp next time.
The German officials can sometimes be difficult. I was travelling on an expired residency permit and a letter explaining that the permit was being upgraded to a more permanent one. The guy at FRA didn't like that my passport hadn't been stamped out. I handed him the permit and letter. He grumbled and let me though.
Another time I got the guy in FRA asking what I'd done in Germany. I handed him my residency permit and said: "Nothing, I live in Switzerland".
