Excuse me.
Yes? What can I do for you?
I just checked in, and there's a problem with my room.
And what is the problem?
I asked for a non-smoking room, and I don't have one. My room smells like cigarette smoke. I can't stand it. Could you change my room, please?
Let me see. . . I'm sorry, but we don't have any more non-smoking rooms. We won't charge you for your room tonight.
Thank you.
I'm very sorry about this.
