Hi, it's Angela and I need to make a service request at 4pm at the Hilton I am staying at. I need more towels.
Hi Angela, what is your room number?
I am staying in room 301.
I am sorry to inform you that your request could not be processed at this time.
Can you try at 4am, I will wake up early and need a shower.
A service person will not be available then either.  Can you select another time?
How about 5am, or 6am at the latest?
Your request has been submitted successfully.
A member of the service team will knock on the door of room 301 at 5 am!
Great! Thanks for your help.
Thank you and goodbye.
