Tipping and donation in Vietnam
Tipping is not expected in Vietnam but it is enormously appreciated. You should consider tipping guides, drivers, and staffs at hotels or restaurants if they have done good jobs.
How much you should tip? It’s up to you and depended on the situation. A good guide normally receives US$10 or more per day. A good driver gets US$5-10 daily.
It’s considered proper to make a small donation at the end of visit to a pagoda, especially if a monk has shown you around; most pagodas have contribution boxes for this purpose.
