Always look for trusted money changer outlets. We’ve heard of this scam before travelling to Bali, Indonesia, and we made sure that we count and check the money before leaving. Make sure that the computation is correct, do your own computation as well. Better search the internet for trusted Money Changer outlets, though the list might be outdated. In Bali, the best money changers are in the city (Denpasar area) near the airport. Rates are better in the city than the mountains and beach areas (Ubud, Jimbaran, etc).
