One or two?

Right. So I'm here in Scotland. I have eaten. I have drunk. I have been to various public and private bathrooms.

It's all the same: There are separate outlets for hot and cold water.

The two outlets are spaced a good ways from each other.

So what do the Scots (and the English) do?

I can come up with a number of suggestions:

1. They always wash their hands in very cold water.
2. They always wash their hands in very hot water.
3. They turn on both outlets and try to move their hands (complete with soap) fast between them.
4. They don't.

Which one is it?
