I really want to sit next to him. ,F: In that case you can sit here, but where is your seat? ,M: It's 7A. It's a window seat. ,F: Oh, that's great. I asked for a window seat. But there were not any left. I really didn't expect I'd get one this way. Thank you.
(A) M: It's okay. You will take 9B as your seat. You don't want a window seat, right? (B) M: No problem. 7A is a good seat because it is next to the window. (C) M: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (D) M: You are welcome. 7A is a perfect seat for you since you do not like a window seat.
