As we were off to get a cab arriving from HCMC we were met by a ''agent'' (for want of a better word!!) immediately I thought-- scam. Shown to a Vinasun cab, so I was a little easier,put the bags in and the agent says ''taxi voucher-200000 dong''. So I said no ,on the meter, I pay the driver. Then he got demanding and aggressive, so I got out of the cab and told him to f off. With that he's off across the car park like a whippet. The drivers really sheepish at this point, and takes us to the Pietro House Hotel for 26000 on the meter. Then I asked him what he was playing at,and told him he was a thief!!! So he's still looking pretty anxious - and wouldn't look me in the eye. But then, I am 6' 4'' so I guess that's why the other bloke made off so quickly.
