Even I never used any Bitcoin ATM. Because afaik, there's no Bitcoin ATM has been installed on my country (India). Hope some Bitcoin ATMs will be installed near in future.
I think you can create and build first ATM in your country. With more than 1 billion India citizen, I sure ATM bitcoin users will increase only short time. In my country (Indonesia) have more than 5 atm, and 1 atm location is near from my city.
