Shops in Tamil Nadu can now stay open for 24 hours, seven days a week. A new state government order permits shops and establishments to remain open round-the-clock for three years. The order has come across as a boon to shopkeepers and traders, especially malls: PVR and Inox; retail shops: Shoppers Stop and Future Retail; and jewellers: Thangamayil Jewellery and Titan Company. If the rule is expanded pan-India, a whole lot of companies will benefit.
