Tipping in Vietnam

Zero. No tipping whatsoever. The locals never do it and would never be offended if they were never tipped.

There are of course some who may expect it and get offended if you don't tip, but only because they have been thus nurtured by Western tourists.

Tipping is akin to child prostitution or being topless on a beach---it is an unfortunate practice that Western tourists have helped to nurture in Asia. If Westerners had never come up to Asia, tipping/child prostitution/being topless on a beach might still exist, but it would be very rare. It is up to you as to whether you want to encourage or discourage the practice of tipping in Asia.

Tipping is not expected in Vietnam, but will be greatly appreciated. Smart hotels and restaurants nowadays add a 5% -10% service charge (which should be indicated on the bill) but elsewhere it’s up to you. In most cases, a few thousand dong will be an adequate tip.

It is customary, though not compulsory, to tip tour guides and drivers at the end of a tour. General practice is around 3$ - 5$ per guest per day for a guide and half the amount for a driver.

There is no tip culture in Vietnam so the tip is not required at bars, restaurants, taxi... If you are satisfied with the service/product and want to encourage the staff, you should give a tip. :)

Actually in a taxi some people leave tip, especially if you got a good service. If you have street food no need, also in local restaurants some local leave tip, but if they do it wouldn't be the 10-15% like in western countries.
