In Thailand I began to wonder how much trade the 7-11's do just from foreigners needing to break large bills, where "large" was 100 THB or more (3.20 USD). Being an American tourist, I always felt guilty about it and would make sure to buy at least a hundred baht of goods if I was breaking a thousand, but I'm pretty sure it was standard to buy a 7-baht bottle of water and calmly collect your 993 baht in change.
