Tap water bottled

I don't know if it's a moral question, a conscience thing. The tap water where I live in the west of Scotland is by all accounts some of the best you can get - perfectly drinkable drinking water. Yet I have in the house bottled water bottled a mere 72 minutes away. At work it's a little different - there are signs at each tap saying that it's not drinking water. And the cafe sells bottles of water at £1 a go. Should I be taking water from my kitchen in a suitable container to work?

I am on the verge of never buying a bottle of water again. Maybe.
