IT was a storm in a beer mug. Only it threw up the dross of racial discrimination that floats under Mumbai's cosmopolitan facade. Cafe Leopold created a furore on June 19 when it denied two South African ladies entry into the pub ostensibly on racial grounds. Though the management retracted its statement later, racial discrimination became a cause celebre with everyone, from director Shyam Benegal to actor Sunil Shetty, denouncing it. The National Human Rights Commission dashed off a showcause notice to state chief secretary P. Subramanyam, expressing shock "to read that the two stewardesses of South African Airways were denied entry into the bar of Cafe Leopold at Colaba only because they were black. As prima facie this constitutes a serious violation of human rights, suo motu cognizance is taken". It instructed Subramanyam to submit his report by August 4, failing which "the commission may proceed to take such action as it deems proper".
