Not flushing a public bathroom in Singapore.
You could face a $150 fine
Bringing cigarettes to Bhutan.
Your punishment will most likely involve several years in jail.
Touching someone's head in Thailand.
It’s considered very rude.
A public kiss in Saudi Arabia.
The typical punishment is 120 lashes.
Stepping over people's legs in Nepal.
Once again, extremely rude.
Giving people the thumbs up in Iran.
It’s actually a very offensive gesture.

This symbolizes a desire to end the relationship.

Stepping on money in Thailand
Keep in mind, the kings face is on the banknotes…
Spitting in Singapore
Similar to chewing gum, expect to be arrested.

Placing your chopsticks upright in your bowl
No matter where you are, if the people use chopsticks this is usually a bad idea.
