The website says the token is valid for 24 hours, if the user is going to have 2-3 coffee/cigarette a day he doesn't have to get a token every time. Also If this token is valid across all the Bakeries and petty shops then the user can go to any shop for a chai and use the internet. Soon people might give you a token as change ;-)

I hope Token as change thing takes off

Big fan of yegor256, don't always agree with him on everything but he writes clearly and his stuff is well thought out.
