Rest Stop Chat

I was driving from Santa Monica on the freeway heading towards
Las Vegas, when I decided to stop at a rest stop.
The first toilet stall was occupied, so I went into the second one.
I was no sooner seated than I heard a voice from the next stall say:
"Hey, how are you doing?"
Well, I am not the type to chat with strangers in a rest stop toilet,
and I really don't know quite what possessed me, but I answered, (embarrassed): "Not bad, thanks."
And the stranger said: "What are you up to?"
Talk about your dumb questions!
I was really beginning to think this was too weird, but I said:
"Well, just like you, I'm driving east on the freeway."
Then, I heard the stranger, all upset, say:
"Look, I'll call you back in a few minutes, there's an idiot in the next stall
answering all the questions I'm asking you!"
