After being away on business, Tim thought it would be nice to bring his wife a little gift. "How about some perfume?" he asked the cosmetics clerk. She showed him a Rs 50.00 bottle. "That’s a bit much," said Tim, so she returned with a smaller bottle for Rs 30.00.

"That’s still quite a bit," Tim complained. Growing annoyed, the clerk brought out a tiny Rs 15.00 bottle.

"What I mean," said Tim, "is I’d like to see something really cheap."

So the clerk handed him a mirror.
