ASSISTANT: Hi, How are you doing? How can I help you?

USER: I am good. Hope you are doing good as well. I wanted to cancel my recent reservation which I made last week for my friend's wedding. Could you assist me with this?

ASSISTANT: Oh sure. May I know your full name please?

USER: My first name is Linda and last name is Clark.

ASSISTANT: Just give me a moment. Hey Linda. I'm sorry, but there was no reservation found on your name. Is there anything else I can help you with?

USER: No thanks.
