For those of you who have two passports:

I've noticed this summer, traveling to Turkey, that German customs officer (I was flying from Canada through France and Germany) were very sensitive about seeing stamps showing which country I entered AND EXITED. I have only one passport so they're all in one spot, but the Germany officer was really annoyed that the French had not stamped my passport when I exited. (I don't know a lot of German but I understood that he was not kind to my French cousins.) When I left Germany on the way back - even just on a stop over - they were careful to stamp my passport. My feeling was that with the tightening concerns over illegal immigration there is more concern for those sorts of things. Maybe that's why they get confused if you use one passport to get in and another one to get out. What do you think?
