"How about some perfume?" he asked the cosmetics clerk. She showed him a bottle costing $50.

"That's a bit much," said Robert, so she returned with a smaller bottle for $30.

Robert grew agitated, "What I mean," he said, "is I'd like to see something real cheap."

So the clerk handed him a mirror.
