A customer walks into a sweet shop in Bhowanipore, West Bengal and asks for a glass of lassi. "Why buy a lassi for Rs 10, when you can get a Pepsi or Coke for only Rs 7?' suggests the shop owner. But doesn't the price tag on the bottle read Rs 10? "Not any more,' says the shopkeeper. "Because the drinks are not selling, we have been told to slash the prices.' Both the companies denied the price change had anything to do with the Centre for Science and Environment findings released on August 5, which found high levels of pesticides in 12 brands of soft drinks marketed by the cola companies and led to a dramatic slump in sales.
