However, many banks worked till late. An official of HDFC Bank in Delhi's Model Town said they disbursed "lakhs of rupees to desperate customers" till late evening but could not cater to all. Those left out were asked to come again on Thursday, the official said, refusing to reveal his name. Earlier, serpentine queues started near banks across the country hours before they opened. Bank officials stood outside distributing withdrawal or exchange forms to customers prescribed by the Reserve Bank of India.
