Buying liquor has gone hi-tech in Tamil Nadu. Swanky automatic liquor vending machines have been set up at four government-owned outlets inside malls in Chennai. The payment can be made online or cash. The opposition, however, said the vending machines will make it easier for minor students to buy alcohol. "How would these vending machines validate the age because liquor is supposed to be for people above 18? They might be even selling beer in pushcarts during summer. Looking at newer avenues for selling liquor to increase revenue is not good for the state, not good for the people," AIADMK spokesperson Kovai Sathyan told NDTV.
