How it works:
- Version 1: the cashier takes your note and swaps it with a note of smaller denomination. You are then asked to top up the difference. A common trick is to swap the 500k dong note to a 20k note as both are blue and look similar.
- Version 2: the cashier takes your money, then claims you have not paid yet.
Places to beware:
What to do:
- Watch carefully after you pass the note over. You can even say out how much you are passing over.
