Topless and shocked, Mille Debray watched her sister scream in pain when they were doused on stage with what looked like blood.The Soap Girls, punk-rocker sisters Mille, 23, and Mie, 22, of Cape Town's Hout Bay, said two audience members at a UK pub threw the liquid at them. They want to take legal action against the pub owner who reportedly called them "sluts"."Mie's eyes burned for hours. I had my microphone repeatedly knocked into my mouth by the individual who chucked the liquid at me," said Mille. "It was hard for my sister to breathe and see."She started screaming she was going blind. But we couldn't stop because we had fans that had driven like six hours to get there."They said they were "hassled" by people asking "what we were doing there from South Africa".After the attack, Mie had "severe panic attacks".Said Mille: "The only good to come out of it was music. We write about our experiences. Bad Bitch is our war cry and our response to the attack. It's about standing up for your right to be yourself."Pub owner Paul Osmond said customers threw "half a litre" of "fake blood" at them in jest at a Halloween bash in November. He didn't instigate the attack and nobody was offended by the nudity.He claimed the duo were late, "unprofessional" and "disrespectful". Police took no action as their instruments were not damaged.Mille said they were touring Europe. The attack still affected them, forcing them to "come out and say we are both virgins"...
