My beef, besides the mercantile effort of BB/WB, et al, is that a public area, that has public crowds, (not that store per se), ought to have a public source of water available...I grew up with these on most corners and in most joints:
The marketeers would bottle air and sell it to us, if they could.
A toss away bottle of water, esp the packaging, freight, cost, etc., is like a nuclear powered weed eater, imo.
