Guest: Hello, I am checking in. The name is Smith.
Receptionist: One moment, please... I am sorry, Mr. Smith, but I cannot find your reservation.
Guest: That is impossible. I booked it two weeks ago. Here is my confirmation number.
Receptionist: Ah, I see the problem. You booked the room for next month, not this month. We are fully booked tonight.
Guest: Oh no! What am I going to do?
Receptionist: Don't worry. Since it was a system error, we will upgrade you to the Executive Suite for free.
Guest: Wow, thank you very much!
