I take it you feel it is not "sensible" to take an intoxicating substance?
A lot of people are pretty closed minded when it comes to this issue. Hell, I was a couple of years ago ... how things change ...
Anyway - yes, I have in the past, and will continue to order water in a pub... I drink 6-8 litres of water a day, so when I'm on the lash I need to get my fill
... definetly not a pints worth. I might have a glass of water, but i'm not a big water drinker anyway. If it's the first thing they were drinking (and not driving) I would find that pretty odd.
