Should I Leave Tips?
Tip your guide around $10 USD per day. The same goes for a private driver. For other services, there are different schools of thought. Tipping is not part of Vietnamese culture, so many foreigners believe that they shouldn’t do it. Some travelers find that traveling in a developing country piques their generosity. Generally speaking, a little extra is appreciated for good service.
Taxi drivers don’t necessarily expect a tip, but passengers often round up their total if they feel they had good service. If you want to leave a little extra for a waiter, a taxi driver, or a masseuse, around 10 percent is a nice amount. Or you can simply round up.
