Avoid getting angry or raising your voice in public places. In Thailand, the people are not confrontational.
Showing anger may embarrass a Thai person and will not help you in your endeavors.
When you visit Thailand, practice patience and copy what the Thai people are famous for - smiling.

Learn the proper Thai etiquette for greeting. When traveling in Thailand, the wai is the proper form of greeting.
Place your palms together with your fingers pointed toward your chin, as if you are praying.
Bow your head a little bit, over your fingers.
Thai etiquette determines how high you hold your hands. If you wai a monk, older person or dignitary, you raise your hands to the top of your nose. Hold your hands near your chest when you wai an equal.
