I was in Hungary once, very late at night, in the middle of nowhere (long story), about 20 years ago. Ended up in the back of a police van. Turned out they just wanted to shake me down for money. Made the universal gesture of rubbing fingers. Showed him my wallet - empty. Very mad. Gave me a piece of paper in about 15 languages that said I was permanently banned from entering Hungary and then threw me out of the van.
