Sometimes I would stop at a garage, and people I was travelling with bought bottled water, and I would buy Coke or Mirinda or Sprite or something like that. Yes, I know it is only sugar and artificial flavouring, but I felt that at least there was some value added.
Then the bottled water people started adding flavours, and I tried a few. I like aQuelle naartjie flavour, and Selzer tangerine, and started to buy them, especially after the price dropped below that of Coke and such things. Selzer and aQuelle claim to be spring water rather than tap water, but a lot of the brands of bottled water are just plain tap water sold at vastly inflated prices.
And the thing that gets me is that a lot of people use that plain bottled water at home, on the table. It's much cheaper and less polluting when it comes straight out of the tap into a jug than putting it into plastic bottles that just get thrown away, and transporting it around the country on lorries.
