There are scams at the airport as well. The fake taxi drivers will pull people from the airport and ask you to ride for a good price. Then he will push you to his friend which has a bigger car.
Once you get on the car, he will ask you for money to pay for parking and it is for a big car. Big cars cost more so when you pass him some money, he will make some noise and snatch your money.
Count them in front of you and then say not enough for big cars so he will push you back to the first guy that approached you. Then you realize you lost some money on the way to the hotel.
I lost about 3 million dong last few months and now my friend’s friend lost 1.5 million dong. Just to let you guys know about this scam. Karma will get him some day scamming tourists like that.
