British plumbing…
From Set Godin, More than twenty years....
That's how long it took after the invention of basketball for someone to realize that they should cut a hole in the bottom of the peach baskets. Before that, you had to stop the game and get a ladder and get the ball out of the basket. I wonder how long it will take for faucets in the UK to be able to generate warm (not cold or hot) water? Any sinks where you work?
