Cambodian society places strong emphasis on politeness, respect and calm behaviour. Greetings are usually friendly and informal, often accompanied by a slight bow or nod. Showing respect for elders, monks and authority figures is important, and public displays of anger or confrontation are generally frowned upon. Modest dress is expected in public places, particularly in temples and rural areas, where shoulders and knees should be covered.
Tipping is not obligatory in Cambodia but is appreciated, especially in tourist areas. In restaurants, rounding up the bill or leaving a small tip for good service is common. Tour guides, drivers and hotel staff often receive small tips, particularly for longer services. In everyday situations, tipping is discretionary rather than expected.
Photography is generally permitted, but visitors should always ask permission before photographing people, especially monks, children and individuals in rural areas. Photography may be restricted at certain religious sites, government buildings or memorials, and signs should be observed. Respectful behaviour and sensitivity, particularly at temples and historical sites, are essential.
