Culture: the wai and everyday respect
The **wai** — palms pressed together at chest or face level with a slight bow — is the Thai greeting and a sign of respect and thanks. As a visitor you're not expected to initiate it perfectly, but returning a wai (except from children or service staff, where a smile or nod suffices) is appreciated. Thai culture prizes calm and 'saving face': losing your temper, shouting, or publicly embarrassing someone is deeply frowned upon and rarely gets results. A smile, patience and a soft voice go a long way. Politeness particles 'krub' (men) and 'ka' (women) soften any sentence.
