If you happen to have Eastern European change with you, (Croatian kuna, Hungary Florint, Czech Koruna), and you happen to be in Penang, I will be happy to change the money with you on a non-profit basis. Reason: I am travelling to East Europe in January, and will be doing road trip, and I am quite worried I don't have change for the buses and subways and bread on the first day of my arrival in east place.
