Greetings: Offer a “sok sabai” (hello) with a slight bow or sampeah (hands pressed together); use both hands when paying for boat fees or purchases to show respect, especially in floating villages like Chong Khneas or Kampong Phluk.
Dress: Wear modest clothing covering shoulders and knees for visits to floating villages or cultural events; a lightweight scarf ($1 or 4,000 KHR) aligns with local norms culturetrip.com. In the dry season, pack lightweight, breathable clothing like cotton or linen; in the wet season, bring quick-dry clothing and a raincoat ($2 or 8,000 KHR).
Behaviour: Maintain a quiet demeanor in floating villages or during community events; ask permission before photographing locals or rituals; avoid loud behavior on boats or in villages.
