Maybe other stores have it, but I know at my store besides a sink or a water fountain there's no self-serve way to get water and I very much think there should be. Customers ask all the time and I always feel bad offering them sink water or a water fountain that doesn't fill their cup all the way. If not a button that adds to the fizz city machines, maybe invest in the nice water fountains that are built for water bottles? Even if people aren't paying for bottled waters anymore (and some still will), it brings people into the store so they'll end up buying at least a snack.
