Hello, how can I help?
I'm Mark. I'd like to see an apartment at Shadyside Apartments. If you have Monday at 12 pm that would be great.
Have you already paid the application fee for the apartment?
Wait, I have to change the time. I have a job interview at 12 pm. Cross your fingers for me. Also, can't remember if I paid the application fee. 
When would you like the viewing to start?
Why don't we try the same day at 5 pm?
Give me a moment to check for you.
Thank you very much! I am nervous about this job interview!
Great, there is still a viewing available at that time. Would you like me to book it for you?
That sounds great. I am interviewing for a sales position. 
Excellent, the viewing is scheduled now!
Thank you so much. I hope you have a wonderful day.
Thank you and goodbye.
