WHEN Kavita Khanna and Meher Anklesaria entered Madness, a discotheque in Hotel Ramee International located in a Mumbai suburb on December 14, they couldn't have known that there was more than plain boogeying in store. They were in for a nasty surprise when they were denied entry. Their crime: they were wearing saris. Says Khanna, a lawyer: " I couldn't believe it at first that the national dress could be considered inappropriate apparel in the heart of the country."
