They never charge for tap water in our Wetherspoons. (Of course they don't allow music either - no connection.)

Here's a link to a great song Matt McGinn wrote about drinking ower much - Troubled Waters Of course Matt wasn't teetotal. More's the pity as it turned out.

I suppose the most widely sung temperance, or even teetotal, song - though it's rare that anyone reads it that way - is that fine old Norfolk song, the Wild Rover.
