After being away on business, Tim thought it would be nice to bring his wife a little gift, so he stopped at a department store on his way home.
"How about some perfume?" he asked the cosmetics clerk.
She showed him a $50.00 bottle.
"That's a bit much," said Tim, so she returned with a smaller bottle for $30.00.
"That's still quite a bit," Tim complained.
Growing annoyed, the clerk brought out a tiny $15.00 bottle.
"What I mean," said Tim, "is I'd like to see something really cheap."
The clerk handed him a mirror.
