Tascha's in Nicolway - European water comes at a high price

Is it necessary to import water from Europe to sell to customers in South Africa? I just had coffee with a friend at Taschas in Nicolway. Expecting to pay a slightly higher than normal price for the experience, I was taken aback when the bill arrived with a R75 charge for a botlle of water. Not only is it unnecessary, it is also completely ******** of the cost to the environment to transport water from Europe to sell in a place where we have some of the best water in the world! I will think twice before visiting Taschas again.
