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.
