After being away on business, Tom thought it would be nice to bring his wife a little gift.
"How about some perfume?" he asked the cosmetics lady.
She showed him a bottle costing £50.00.
"That's a bit much," said Tom, so she returned with a smaller bottle for £30.00.
"That's still too expensive," Tom growled.
Growing annoyed, the lady brought out a tiny £5.00 bottle.
"What I mean," said Tom, "is I'd like to see something really cheap."
So the lady handed him a mirror.
