I second this. Living in Germany I am blessed with the best of German water heating technology, which includes mixer taps (faucets). Whenever I go back to the UK to visit family, I end up scolding myself on the hot tap. My theory is that Brits either don't wash their hands, or if they do, they have a limited amount of time before the hot tap becomes too hot!

The trick is to move your hands to and fro between the two to keep the temperature ambient.
