In The Men's Room

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 restroom but I dont know what got into me, so I answered, somewhat embarrassed, Doing just fine." And the other guy says: "So, what are you up to?"
What kind of question is that? At that point, I'm thinking this is too bizarre so I say, "Uh, just traveling." At this point I'm just trying to get out as fast as I can when I hear another question: "Can I come over?" Okay, this question is too weird for me but I figured I could just be poliete and end the conversation. I tell him, "No, I'm a little busy right now." The I hear the guy say nervously... "Listen I'll have to call you back. Some idiot in the other shall is answering all my questions."
