What I like is how those "big three" booths in the basement area of BKK's MTB all rate matched each other and the forex ladies are all competing for cx by shouting "same rate, same rate" all at once. There have been instances where I just popped over to K-Bank booth (which usually has a terrible rate if you go to the ones on arrivals / departures level.) or even the yellow one since the green SPR queue was incredibly long.
