I got stopped by customs official. He checked my bag and said that my video that had bought duty free in Singapore was contraband. He wouldn't give it back to me. I refused. He locked it away and told me to comeback with the money. I was fortunate that my uncle in Athens was a police inspector. We returned a few days. later together. He flashed his police ID to the official who was shocked and 5 mins later my video was returned to me!!!!
