Pointing at another person with one's index finger or feet is considered rude. The soles of one's feet should never be pointed at another person. One should sit in a way that avoids this. Feet should also not be rested on tables or pillows that people sleep on.

In Thai culture, the most significant signs of disrespect involve the head and the feet. The head is considered the most sacred part of the body; touching a Thai person's head—even a child's—is seen as a major insult. Conversely, the feet are seen as the lowest and "dirtiest" part of the body. Pointing your feet at someone, a statue of the Buddha, or the King's image is profoundly offensive. You should also never step over someone or use your feet to close a door. Additionally, the Thai Monarchy is revered with extreme devotion; making any disparaging remarks or even stepping on a coin (which bears the King's face) can lead to legal trouble under Lèse-majesté laws. In social interactions, "losing your cool" or shouting in public is considered a lack of "Jai Yen" (a cool heart) and causes "loss of face" for everyone involved. Lastly, always remove your shoes before entering a home or a temple as a sign of respect and cleanliness.
