Thai people are courteous, peace-loving and look downward on open showdowns. Also, do not show your impatience or frustration because it is considered a sign of weakness. The Thais believe that all conflicts and issues can be solved with a smile.
At a temple, you are required to wear a full leg covering pants or skirts. Women should not touch monks and everybody is expected to remove their shoes while entering a local's house or a temple. In public safe distance from people is appreciated. The Thais usually do not shake hands as well.
