One evening in 1993, Mits Sahni was standing in a queue in Leicester Square in central London. He was trying to get into a nightclub - but when he got to the front of the line he was turned away by the bouncer.
It wasn t the first time this had happened. He d tried different approaches - bringing along female friends or wearing smarter clothes. But the result was always the same. The doorman would make up excuse after excuse. And after a while you figured out it was due to racism.
