Sign of the Times

I decide to stop at one of those rest areas on the side of the road. I go into the washroom. The first stall is taken, so I go into the second stall. I had just sat down when I hear a voice from the other stall.

"Hi there, how is it going?"

Okay, I am not the type to strike up conversations with strangers in washrooms on the side of the road. I didn't know what to do, but finally say: "Not bad."

Then the voice says:
"So, what are you doing?"

I am starting to find this a bit weird, but I say:
"Well, I'm going back east."

Then I hear the person, all flustered, say:
"Look, I'll call you back. Every time I ask you a question, this idiot in the next stall keeps answering me!!!"
