But they are also promoting getting rid of the existing water fountains, which typically are already using water that has been cleaned and filtered by their local system. If they succeed, you have to use their service instead of just leaning over and drinking. As adults, many of us do have water bottles, but very few children that I know do - they just drink from the fountains. Making it harder for kids to drink, while inflicting ads on adults who just want some water doesn't sound like a great business model to me.
