Potty Talk

We left Dallas/Ft Worth heading to the Gulf Coast, when I needed to stop at a comfort station. The first stall was occupied,  so I went into the second one. I was no sooner seated than  I heard a voice from the next stall: 
 
"Hi, how are you doing?"

 Well, I am not the type to chat with strangers in highway  comfort stations, and I really don't know quite what possessed me, but anyway, I answered, a little embarrassed:

 "Not bad."

 And the stranger said: "And, what are you up to?"

 Talk about your dumb questions! I was really beginning to  think this was too weird! So I said:

 "Well, just like you I'm driving west."

 Then, I heard the stranger, all upset, say, "Look, I'll call  you back, there's some idiot in the next stall answering all  the questions I am asking you."
