I only saw three scams while I was there, two in Hanoi, one in Saigon. The first involved a very attractive girl coming up to my husband and saying that she wanted to learn how to speak English better and that she was a uni student. We knew about this scam already though. Basically she gets chatting with a bloke, gets him to take her to lunch to a cafe of her choice, has him pay an exorbitant amount for it and she gets a cut. When I eventually walked up behind him she said something in Vietnamese, hopped on her boyfriend's bike and sped away.
We also saw a US$100 note just lying on the ground. None of the locals were picking it up, and that was equal to about 1 million dong. More than some earn in months. I stood by it for a bit, trying to see who the scammer was but nobody was watching me (in any obvious way, at least) so I just walked off. I wanted to take a photo but you never know who may have popped up asking for money.
The saigon one was a Taxi from the airport. He had his meter on then started on about airport tax and said we had to pay 250,000 dong for the trip. I couldn't be arsed arguing after a long flight and agreed. The actual fare was about 120,000 dong. $5 was 100,000 dong. If they try that on you say you will only pay the meter. Don't put your bags in the boot, as they may try and hold them for ransom if you don't agree. Mai Linh and Sabaco are very trustworthy so try and use them. They're EVERYWHERE.
The tourist areas are VERY touristy. Cu Chi tunnels, Halong Bay etc. Absolutely go there, but try to do some other things too. If you can hire a river boat with a local and get them to take you around. Go to Phu Quoc island and walk around Dong Duong and chat to the kids who run up to you. Get a taxi (Mai linh, Sabaco are trustworthy and use a meter)
Vietnam was lots of fun, whenever you haggle, do it with a smile and don't be afraid to walk away. The next shop will have the same stuff!
Yeah it sounds familiar. Two quite young girls who were in our tour group got smashed badly by a taxi from the airport. They were in tears once they met up at the group orientation and the tour guide told them they were ripped off. They paid something close to 100 Aussie for a less than 10 dollar ride.
I got scammed in Hanoi by two different camera shops. Once on a camera battery and once on an SD card. They didn't seem like dodgy places either, brightly lit, located in busy shopping areas, covered in all the legit stickers (official dealer etc.), posters, advertising, etc. They were full of proper equipment, high-end as well. So it was a real shocker. Both items didn't work. I knew about trying things in the shop before you buy, except these places wouldn't let you open the packaging. Though they would show you another one from the "same batch" that worked of course.
My other one was a pair of cyclo drivers in HCMC who enticed us in with a good rate to go to a post office and then the War Museum. Once we had arrived they asked for 10 times the amount, which is pretty common. It seemed unusual that they didn't stop right in front of the museum at first but when we had realised the tourist police were stationed there we knew why.
It wasn't much in the end anyway, probably about 15 bucks and I felt a little sorry for these guys who were about 50 odd years old and they had just killed themselves cycling around in the hot sun. I just didn't like the way they went about it, if they were upfront in the beginning it would have been OK.
