Receptionist:   Hello. The Gresham Hotel. Felipe speaking.

Client: I'd like to book a room, please.

Receptionist:   Certainly, sir, how long would you like to stay?

Client: I want a single room, en suite, for the night of Monday the
1st of September and Tuesday the 2nd. Then again on Friday the 5th of
September.

Receptionist:   I'm afraid we have no single rooms free on those dates
but we can offer you a double room for single use.

Client: That's fine. I may want to stay an extra night.

Receptionist:   I'm sorry, sir. The hotel is full on the 6th and 7th.
