Bathroom Conversation

I was barely sitting down when I heard a voice from the other stall saying:
"Hi, how are you?"
I'm not the type to start a conversation in the men's restrooms at a rest stop but, I don't know what got into me, so I answered, somewhat embarrassedly: "Doin Just Fine!"
And the other guy says: "So what are you up too?"
What kind of question is that? At that point, I'm thinking this is too bizarre so I say: "Uhhh I'm like you, just traveling east!"
At this point I am just trying to get out as fast as I can when I hear another question.
Can I come over to your place after while?
Ok, this question is just wacky but I figured I could just be polite and end the conversation.
I tell him, "Well, I have company over so today is a bad day for me!"
Then I hear the guy say nervously..."LISTEN!!! I'll have to call you back, there's an idiot in the other stall who keeps answering all my questions.
