Hi. I want to schedule a viewing or North Hill apartments on Wednesday at 8 pm.
Could you give me your name, please?
Sure, it is Angela
Have you already paid the application fee for the apartment?
I do not recall. 
I am sorry, but there is no viewing available at your preferred time.
I just remembered I have a job interview at that time. Can you change the day to Thursday?
I am sorry, but there is no viewing available at your preferred time.
Do the apartments have enough rooms for kids? What if I decide to have a baby one day?
I am sorry, I don't quite understand what you mean. I am only able to help you book apartment viewings.
ok, book any day except the day I have the interview. The new job pays more and I will need the extra in case I ever have a baby. 
I am sorry, but there is no viewing available at your preferred time.
you can change the time
Great, there is still a viewing available at that time. Would you like me to book it for you?
yes
