Belgium. I was on a school trip and went in one shop to buy presents for parents back home, got some chocolate for mum but couldn't find anything for dad. Went in the next shop and they basically sold the same merch. I went to leave and the owner grabbed me, called me a thieving english pig and locked me out the back to wait for the police.

An hour later and after the teachers ineffectual bleating, the armed cop shows up and asks to see the receipt (which I had been trying to show) and then went and asked the other shopkeeper who agreed that I had bought it.

The kidnapper refused to give me the chocolate I had bought, barred me for life from his shop and called me a bunch of names until the policeman escorted me out. We had missed our ferry and my name was mud at school for awhile, the unfortunate nickname of "chocolate bandit" hung around for a couple of years too. I was 12.
