As demonetisation of high value notes hit small businessmen across the city, sex workers of Sonagachi, South Asia's largest red-light area, here are seeing brisk business as they are accepting high denomination notes. "Our girls have been asked to accept Rs 500 and Rs 1,000 notes. But they are telling customers that they will not accept those after this week. Therefore there is a huge rush of customers. "Although sex workers in top categories are facing no problem but those who take only Rs 300 to Rs 400 are facing great difficulty," said Bharati, the mentor of the Durbar Mahila Samanwaya Committee, a sex workers' organisation which claims to have over one lakh registered sex workers under it across Bengal.

Sex workers who charge below Rs 500 are facing tough time as they have hardly got any customers in the last two days. Prospective customers first inquire whether the sex workers will accept Rs 500 and Rs 1000 notes. "If we say no, we will lose the customer. We have to accept the notes and Durbar and Usha bank had assured us that our money will not go in waste," said Rekha, a sex worker.

In the last two days, sex workers in and around Sonagachi have deposited more than Rs 55 lakh in Usha Multipurpose Cooperative Bank, which was formed and is run by former sex workers since 2001 for women in the same trade. "Due to the huge rush of customers in Sonagachi, the sex workers in last two days have deposited more than Rs 50 lakh in their bank accounts in Usha Bank. Generally sex workers prefer to keep money in their homes but after demonetisation, there is a rush among them to deposit the money in the bank," Shantanu, a senior official of Usha Bank said. In normal circumstances, Usha Bank carries out a business of around Rs five lakh per day.
