Going abroad has its own problem. One of them is about the exchange rate. Going to Indonesia means than you should know the exchange rate from Rupiah to Dollar. But one thing more important is, how much the reasonable price of things in Rupiahs is. I once go to Thailand and had a dinner. Then the bill come and we paid the bill. After that, the waiter kept waiting near us, perhaps looking for some tips. Since we don’t really know the range of price in bath (also that was our first night in Thailand), we only tipped him about 0.1 dollar! He looked disappointed and then left us. We talked about that and later we realized that was only 0.1 dollar, no wonder he felt sad LOL
So, what will rupiah gives to you?
