recycled mineral water bottle

While I was pregnant with Emma, I noticed some of the big name restaurants in Jakarta are re-using water bottles and just refill them with dispenser water!! I find it very cheap of them to do so and of course very very unhygienic!! What if, the previous drinker actually drank the water directly from the bottle?! That was when I started noticing all these opened mineral water bottle and I've been demanding sealed mineral water from then on!
