A: Miss. I have a lower back pain. May I have one more blanket and two more pillows?

B: Sure. Here you are.

A: Thank you. By the way, would you show me how to turn on the reading light?

B: OK. All the buttons are on the seat arm. See, this one with a picture of a light bulb is for the light. That one with a picture of a girl is service button. All the buttons have pictures on them. You won't mix them up.

A: I see. Thanks again.
