Traveling to new places helps you learn about other people's culture. You tend to appreciate the variety of activities life has to offer.
Tuk tuk. One of the transportation to get you to the place you wanna go. They start with 3$. You ask for 1$. You end up meeting half-way. The fare now becomes 2$. That's it if of course, you're a foreigner. When you stay longer and know their way of life by heart, you'd be dealing with Riel, Cambodian's trade currency... and probably pay 1,000Riel only. ( 1$ = 4,000Riel)
