There have been many threads on here about life in Vietnam. The following exemplifies a portion of that life:
I took a Grab taxi to the airport in San Bon this week. Forgot my new iPhone 7 plus in the Taxi as I departed. Realized it as he was driving away. Asked someone if I could use their phone to call my phone. The driver did not answer the phone. Called again and had a very kind employee at the McDonalds at the airport speak to the taxi driver. The driver said he would return with the phone. He was still on the airport grounds and appeared in just a few seconds. Got my phone back and gave him 100,000 and for his trouble.
Upon my landing I received a call from my friend who had ordered the Grab taxi on her phone that the taxi driver was livid over the amount I paid him to get my phone back. He wanted 2,000,000 vnd. He even went so far as to demand my friend pay him.
In many countries oil the world the driver would have simply returned the phone and been ticked pink that you gave him something for the time wasted to return it.
