Snowy still water surprise

What a delight, descending upon Heathrow from Dakar 2 days ago (on a BMED flight), to hear the captain announce that London had been covered in a blanket of snow the previous day! In my experience, snow (or at least snow that sticks) is quite rare there.

But I had a bigger shock when a friend and I sat down to eat at Sofra (a Turkish chain) in my old stomping grounds of St. John's Wood, and the waiter brought us the still water that had been ordered. Having been in Africa for the past month, such highly-advanced packaged and marketed products seem other-worldly. I mean I really did a double-take when served such "high-class" hydroxylic acid.
