I'm a bit worried about the small-time merchants and dealers.
They don't have enough money to pay the worker force or buy new stock of goods. I have a lot of friends who do manual labor in construction field, they usually receive a 500 rupee note at the end of the day, most of their bosses have ran out of 'cash in hand', they have bank balance, but they cannot withdraw it.
Lets hope that won't deeply effect the economy...... "You Should (Almost) Never Rewrite Your Software"
