108. No Free Lunch
Hoping to get free contact lenses， Freddy goes to the optician.
F： Could you help me check my eyes. Please？
O： Sure. Please have a seat and put on these glasses. Now， tell me. Which letters seem clearer？
F： The ones on the right.
O： Ok. Can you read these price tags？
F： Yes. They’re as clear as daylight.
O： Fine. Read out the highest amount.
F： US$100.
O： Right. That’s what it’ll cost you.
F： But I thought the contact lenses are free.
O： Yes. But you’ll have to pay for our service.
F： No wonder they say， "there’s no such thing as a free lunch."
