We tried to rent a bike at Mountain View Hotel. They insisted USD $10 for a bike per day. I felt that it’s too expensive. Later a guy approached us on the street, willing to rent us his Honda motorcycle for USD $6 a day, or USD $7 inclusive of petrol. So we made a deal for the bike and petrol.
Later he told me that he needed money to eat today. So he hoped that I can paid him in Vietnam Dong for VND 110,000. He looked a bit pity, may be just a trick to get more in Dong, as exchange rate there were not so good.
