Hello
What apartment are you interested in?
I'm scheduling a viewing for One On Center Apartments for Tuesday at 2pm
Is there anything else that I can do for you?
My name is Alexis and I just remembered I can't make it for Tuesday at 2pm because I have a hot date, is there another time available?
I am sorry, I don't quite understand what you mean. I am only able to help you book apartment viewings.
I need to book a new time
Whats a better time
How about Wednesday at 2pm
Not available, im sorry 
What about at 4pm or 6pm
I am sorry, I don't quite understand what you mean. I am only able to help you book apartment viewings.
Please check if there is any available time on Wednesday by querying the time slots
Excellent, the viewing is scheduled now!
Great, hopefully my date will go well, thanks again
Thank you and goodbye.
