The water in the bottles is different.
People paying a premium for something they could get from a fountain or a faucet is nuts. Why don't they just buy their own Nalgene bottle and carry it with them?
There was a recent report on TV about Cook County IL also running up a huge bottle water bill. Some lady on the board was interviewed and said well I need this water as oppose to the drinking fountain water because I am on the cook county board.
