• Thai culture places certain spiritual importance to certain parts of the body. You should not point your feet at people, touch people with your feet, prop your feet up on seats or tables or step over people sitting on the ground. The head in contrast has a much higher importance. Avoid touching people on the head as this is considered very rude. You should also avoid sitting on pillows meant for head rests. In some rural areas, food is often served while seated on the ground. Stepping over food on the ground is another extremely rude gesture and will surely embarrass your Thai host. - See more at: http://www.isvolunteers.org/blog/thailand-cultural-norms-and-traditions/#sthash.xMKjBDAM.dpuf
