Ashok Khemka is known for having exposed cases of alleged high-profile corruption, such as the Robert Varda-DLF land deals and the pesticide scam in Haryana. But last month, he took up another worthy cudgel. Travelling on a Rajdhani Express from Delhi to Allahabad, he found the train dirty, food unsatisfactory and had to endure a delay of about 13 hours. But he couldn’t get any complaint book on the train. “The staff kept making excuses and even promised me a special dinner. But they just wouldn’t give me the book.”
