ATMs are widely available, including in all major tourist centres and provincial capitals. Credit cards are accepted by many hotels and restaurants in larger cities.
Tipping is not traditionally expected here, but in a country as poor as Cambodia, tips can go a long way. Salaries remain extremely low and service is often friendly and attentive. Many of the upmarket hotels levy a 10% service charge, but this doesn’t always make it to the staff. If you stay a couple of nights in the same hotel, try to remember to tip the staff that clean your room. Consider tipping drivers and guides, as the time they spend on the road means time away from home and family.
It is considered proper to make a small donation at the end of a visit to a wat, especially if a monk has shown you around; most wats have contribution boxes for this purpose.
