State Bank of India

In Bihar Sharif, there are 4 SBI branches. In none of them, GREEN CHANNEL works properly. Most of the days it remains fail. Even the day it works, you need to swipe twice or thrice or wait for luck. In the three banks, each have two Green Channel machine but they say only one may work, other is permanently non-functioning. And on that one you have to attempt your luck.
Out of 20 to 25 tries, I've got only one day when it was working without any problem.
