Taxi tip in HCMC

Whenever we want to go somewhere in a taxi, we give them a "name card" from a store or restaurant. It's a business card! If you are going to a popular landmark, you can just give them the name of the place. But if you have a name card, it's a sure way the taxi driver knows that where you want to go. It also saves on taxi fares since it's a direct route. Other wise you could be taking a grand tour of HCMC!
