Doesn't anyone here ever go in a supermarket? A six pack of 500ml
mineral waters costs about £2 (supermarket own brand). Buying in bulk
reduces the price.

Yes, but I am trying to avoid carrying a bag with me so I don't really
want to take two bottles in (one for the journey in, one for coming
back) because I've stocked up at home. Incidentally, I take water
because it's common sense, not because of the announcements telling me
to do so in case I was too silly to work it out myself!!

If I'm out and want a drink, I'll go to the nearest newsagent and buy
one even if I have loads at home. If I was buying mineral water for
home, I'd buy larger bottles because it's a huge waste of time getting
all that additional packaging for a 0.5 litre bottle.

Tap water does me fine anyway, so if they had tap water available at
stations I'd simply use that. I only drink it to rehydrate, not to be
seen drinking a fancy brand (but, I wouldn't have paid Coca Cola to
drink bottled tap water either!!).
