I think that part we'll never really know. I wouldn't put it past the customs agent of any country really to claim that it was the other end that said they couldn't come in. It's just too fishy of a story to really believe that it happened. I'm far more willing to believe it was just the customs agent trying to deflect blame so they wouldn't have to deal with it.
