Hello.
assistant
My friends planned for the get together, but some of my friends are unable to come because they have final examinations, so I would like to change my existing reservation. Will you check my reservation and modify the ticket please?
user
Sure, let me check our database. May I know your name to change your reservation?
assistant
My previous reservation is confirmed with the name Larry Wilson. So please check with this name.
user
Sure, please hold on for a while.
assistant
Ok, I will wait, take your time.
user
Sorry Larry, we could not find a reservation by your name.
assistant
It's ok, thank you for checking.
user
Thank you for choosing us.
