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 assistant.
She showed him a bottle costing £50.00.
"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 assistant handed him a mirror.
