I had to think about that for a moment. Our kitchen sink has a single hook. The cold water hooks to the right. But you are right about the light switches. In the pub I can order a pint of beer. My wife will have a wine which is metric 250 ml. Confusing innit.............Ya but you guys have the hot water on the right, cold on the left, and light switches are down for on.
I get very confused when in the Isles. Except at the pub.
