Thai Baht

The strongest currency of Southeast Asia, it is sub-divided into satangs.
In Thailand, it is very rude to carry banknotes in the back pocket as they bear the portrait of the monarch, who is a highly respected person. In addition to this, it is also highly disrespectful to step on the banknotes or coins.
The shape, size and weight of the 10-baht coin are similar to those of the 2-euro coin, consequently, many vending machines would also accept this coin, though it is worth about one-tenth of the value of the 2-euro coin.
Some spreadsheet programs (eg. Microsoft Excel, OpenOffice.org) include a function which converts a number into a Thai text if you enter the name of the currency and the change as well. This is interesting because such functions were originally made for the Thai language only.
