On the airport, if you want to fly to another country, you normally give up your bags, they check them, then they check you and your hand bags..., no not if you want to come to america...
the instant you decide to enter america, you need to give your fingerprints, and retina scan.. then you have an extra shelter just for america, where everyone has to take off the shoes, belts... then they check your bags, after which you have to open them, so they can tell you that your cosmetic bag spilled, then you go to another person who checks your handbags and tells you to open that one TOO, so you do that, so that everybody can see that you have all kinds of crap in there, then it takes you about half an hour to put everything back in and then they check you, while it beeps and beeps... until they decide that were the metal things on your jeans...
i think that is something you only find if you want to go to america..
