Restroom 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, bye!"
