If anything, bottled water provides convenience. When you are out on unfamiliar territory and almost certain that you cannot find any good clean source of water, bottled water always offers an alternative. The good news is that most of the stores sell it and if not, there is always a vending machine that is around that does the same. But convenience is not the only thing since there is also the guarantee of safety when it comes to the kind of water that you drink but that primarily depends on the brand that you go for since some are good and others are not.
