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 worker.

She showed him a bottle costing $50.

“That’s a bit much,” said Tim, so she returned with a smaller bottle for $30.

“That’s still quite a bit,” Tim complained.

Growing annoyed, the worker brought out a tiny $15 bottle.

“What I mean,” said Tim with a sigh. “Is that I’d like to see something really cheap.”

The worker handed him a mirror.
