Indirect flights, from Belgrade(non EU) we fly to a German airport(EU) the bags go to the next plane without checks.The flight is then EU to EU so there are no custom checks.
We had a family friend in the 60s who was quite famous for 2 things.
1 his sculptures.
2 he sailed into New York in a yacht with a huge amount of ganja on board, the yacht was being followed, the customs gave him clearance and waited to catch everyone, he sailed off after a few hours, the feds followed the wrong yacht. The feds caught him but the money and ganja was never found.
I was married by a judge, I should have asked for a jury.
