Thanks very much for posting that information.
While dealing with Bremen (?) did you ever get the sense that they resented the fact that you were making the arrangements from outside Turkey, and that you were being given an exception to get you out of their hair? I ask because a lot of current OW activity (inferred from posts here) suggests that they've taken notice that not everyone who buys an OWE starting in Turkey is Turkish, and would like to clamp down on that.
