It's always good practice to look up basic etiquette before travelling to a new destination. This simple act ensures that you won't unnecessarily be offending the locals and can instead focus on enjoying yourself. Similar to most nearby Asian countries, Thailand regards the concept of face with great importance – in particular, the act of saving face. Essentially, this would mean actions which seem to be directly confrontational or just losing control of one's anger are frowned upon. Additionally, displaying negative emotions out in public is seen as undesirable. Traits such as humbleness, generosity, and modesty are also qualities that are revered here in Bangkok and Thai culture. As such, if possible, try not to dress extravagantly while you're here and refrain from acting out and being flamboyant when in public places.
