"Are you sure?"
"Yes. You followed the wrong carriage; that is all there is to it."
"Well," admitted the cabby, "I think you are right. Where shall I take you now?"
"Nowhere; I'll walk. How much do I owe you?"
"Ten dollars," was the calm reply.
"Dollars."
"Ten dollars for driving me that short distance?"
"Do you call that a short distance?"
"Yes; I could have walked it in a good deal less than half an hour."
