People here have a particular way of exchanging money. For the Chinese it's a way to signify the preciousness of what's being given and received - even if it's just $4 for your laksa or carrot cake. For Hindus it has to do with the flow of prana. Whatever the reason, money is typically given and received with both hands and with a slight bow of the head. It's very subtle, but once you start noticing it you begin to see the transactions differently. The solemnity given to the everyday manifestations of what might often be labeled crass commercialism...well, it makes you think about the person on the other end and about the privilege of being able to take part in the trade. And as a traveler, it's a special feeling to learn about these little cultural subtleties and to take part in them.
