It's happened to us all. You're having a wonderful day out on the beach, miles from anywhere, the sun is shining; Things couldn't get better than this.

And then, disaster. You need to go.

Moral dilemma time, do you trudge all the way up the beach to find the loos, and if you do, will they be closed?

Or do you take the path of least resistance and wee-in-the-sea.

The problem comes when you make the decision and someone snaps you at it.
