Passport... This is the second time this year I have heard 'we have never seen one of those before' Earlier this year they wanted to take mine and the one from the Swiss traveller with me to photocopy for training purposes.
This isn't a small airport such as GRR (actually, GRR has a lot of Germans travelling there and they are very German-friendly), it's the capital of the United States of America, with masses of international travellers coming through here every single day, showing their passports at the TDC.
