Explanation
In Thailand, pointing with the index finger is considered impolite and aggressive, as it is associated with accusing or summoning someone like a dog. The culturally appropriate way to indicate direction or an object is to use your whole hand with the palm facing up, or to gesture with your chin. This norm is deeply rooted in Thai concepts of respect and non-confrontational social interaction.
Local Tip
Instead of pointing, gesture with your chin or use an open hand, palm up, to indicate a person or object.
