A few days ago, as I was leaving Safeway, I saw a pony-tailed, gray-haired man take 2 empty 5 gallon water jugs from the back of his Volvo station wagon. He put them down in front of the "Pure Water" vending machine.
I watched as he put one of the jugs in the
machine, put his quarters in the slot, and started filling the jug. I
went over and offered to show him where his water was coming from. I directed his attention to the water faucet that was about a foot from the vending machine. It had a copper line that branched off the faucet and went to the back of the machine dispensing "Pure Water".
