Okay, so obviously you know not to smuggle drugs when you’re abroad. But what about the laws that you didn’t know about? Some countries have some pretty obscure laws and traditions that they can be very serious about.

Here’s a rule you may not have heard of: It’s illegal to wear camouflage or military-style clothes in several Caribbean countries, including Jamaica, Barbados, and Antigua.

The same rule applies for civilians in Zimbabwe.

That’s especially important to remember when you’re arriving at the local airport.

Don’t be tempted to go “au naturel” in India, because nude sunbathing is illegal, even in holiday resorts like Goa.

In the United Arab Emirates it is a criminal offense to eat, drink or smoke in public—from sunrise to sunset—during the holy month of Ramadan.

And you really have to watch yourself in Singapore, where you can be fined if you’re caught littering, jaywalking, spitting, feeding birds in public places, chewing gum on the subway, or failing to flush public toilets. (Don’t worry, you can spit as much as you want in your own hotel room.)

And in Thailand, don’t defame the King in any way.

That includes destroying Thai bank notes which are printed with his image.

That can get you sent to prison for 3 to 15 years.
