Well this will be an everything else post. I eat out on the street in Chiang Rai and love it. Great food great prices BUT the ATM gives me 1K Baht notes and they are about useless when I want to buy a 50 Baht meal. I just feel it rude in your face to pay with a big paper bill to pay for a small amount due. I just opened a Bangkok Bank account with debit card, but even if I pull out 5K Baht I am given 5 1K notes... Any constructive advise is very much welcome. Was not a problem before as I would buy a couple three packs of the beer for my room with a 1K Baht note so always had smaller denominations notes, but passing on the beer till I can drop some weight.
TLDR : Answer Summary
The post discusses the challenge of getting smaller denominations of Thai baht after ATM withdrawals, particularly when paying for inexpensive street food in Chiang Rai. The original poster notes the inconvenience of receiving 1,000 baht notes that are difficult to use for small purchases. Comments offer various solutions such as withdrawing specific amounts like 400 or 900 baht, using QR code payments through a banking app, and purchasing inexpensive items at 7-Eleven to break larger bills.
