Well, that's promising. Although I don't recall ever seeing a Super-rich in Phuket (where I'll likely be trying to make the exchange).
Kasikorn et al probably offer the same thing.
Super Rich is a money changer. Money changers give you better rates and they often accept currencies that banks don't...like Scottish pound notes.
Kasikorn is a bank. You'll get lower rates that at a money changer but they still probably take Rupiah..AFAIK Indonesian Rupiah is exchangeable outside Indonesia, (unlike Kip, Dong, Kyat, Scottish pound notes etc).
Cranky - you didn't actually pay did you?? I successfully managed to talk my way out of two traffic fines.. but it took 1/2 hour of patiently chatting on the side of the road......
