My first experience stepping off the plane in Cambodia was being scammed by the official issuing visas. It was $20, I gave him $50, and he didn't want to give any change back. Scams were the defining part of the tourist experience there.
I agree about digital payments, but one of the things that I found disappointingly complex about Bitcoin is needing to receive change when making a payment (https://en.wikipedia.org/wiki/Unspent_transaction_output).
I only made a few Bitcoin transactions because I found the whole experience did not feel like the future. That was a while ago now, and as other commentors have pointed out, it not seems obvious that the real value in Bitcoin lies elsewhere.
