Excuse me , but please empty your pockets of all the metal things and put them in this tray .   Including my keys ?   Yes , and please step over there .   All right . What shall I do now ?   Just open your bags so we can check them . After that you can pick them up right behind that X-ray machine .   I've got film in my bag .   That's all right . This machine will not damage the film .   That's fine .   Can I have your boarding pass ? We need to stamp it .   Sure . Here you are .   Thank you .   Am I through now ?   Yes . Here is your boarding pass .   Thank you and goodbye .
