Arrived hcm this evening, 5th may.
Arranged taxi inside the terminal, no problems with getting the taxi.
THEN, the scam coming thru the airport gate.
The driver paid to got thru then tried to pass the ticket back and ask for $5 us.
I said that I had been to HMC 4 times previously and we do not pay.
He just said ok.
Then windows down and no a/con.
Thanks to the tripadvisor who wished the ta community up to this scam.
