can anyone explain to me the new card system at the bridge. On my way out I was told i didnt need a card and was let through, but coming back they insited i buy a card for one thousand kip which they said was the imigration fee. It was Thursday 3.30pm. I asked to see the head officer to explain to me but he couldnt. He gently led me through without getting a card.! Is it some kind of joke?
