I needed to pay a visit, so I found a public toilet that had two cubicles. One of the doors was locked.
So I went into the other one, closed the door, dropped my trousers and sat down.
A voice came from the cubicle next to me: "Hello mate, how are you going?" Although I thought that it was a bit strange, I didn't want to be rude, so I replied "Not too bad thanks." After a short pause, I heard the voice again "So, what are you up to?" Again I answered, somewhat reluctantly, "Just having a quick poo...How about yourself?"
The next thing I heard him say was ..... "Sorry mate, I'll have to call you back. I've got some d/head in the loo next to me answering everything I say."
