After being away on business for a week before Christmas, Tom 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 bottle costing $50.
"That's a bit much," said Tom, so she returned with a smaller bottle for $30.
"That's still quite a bit," Tom groused.
Growing disgusted, the clerk brought out a tiny $15 bottle.
Tom grew agitated, "What I mean," he said, "is I'd like to see something really cheap."
So the clerk handed him a mirror.
