What does the woman do?

W: Good morning. Can I help you?
M: Good morning. I think there should be a room booked for me in the name of Tony Marshall.
W: Um...just a moment. Yes, one single room with a bathroom?
M: That’ s right. I’ m here to attend the Sun Sea and Sand Exhibition. Does that mean I get a discount?
W: Yes, there is a 20% discount. Is it for 10 days? Is that right?
M: Yes, until the 15th. That’s 10 days.
W: Good. Now, I need to have your credit card. But when you check out, you can pay by card or cash or check, as you wish.
M: Okay, thanks. I’ll pay by this same card then.
W: All right. Mr. Marshall, you are in Room 207. Here is the key. The lift is over there on your right.
M: Thank you very much.
