Lao currency is called Kip -- counted out in the marketplace by the tens of thousands. It's no wonder this lady appears uncertain. (I never could keep the exchange rate straight.) Whenever I am shooting in a marketplace, I am looking for the moment of transaction. Money changing hands often brings revealing reactions such as this one. There is incongruity in this situation as well. The woman accepting the money is wondering with one hand while receiving payment with the other. The customer doing the paying is nonchalantly shelling out what appears to be a small fortune.
