The taxi driver I got at the Hanoi airport was as dodgy as they come. He first agreed to using the meter, then once we started driving asked for more in American dollars, then asked for 500000 dong (Viet currency). I refused on both counts repeating “Meter, Meter.”. He then got lost which drove up the fare and finally insisted his dodgy Meter said 440000 when it actually said 410000+. Some of the digital numbers were very hard to read. I gave him 500000 (only had 370000 in smaller money after the meal). He then claimed he did not have any change and kept saying “Tip, Tip!” I insisted on some change and eventually he coughed up some, he gave me 50000 dong back. The trip from the airport to the hotel ended up costing 450000 dong, $25.21 CAD.
