Hi, I'd like to view an apartment. 
Could you give me your name, please?
My name's Mark and I wanted to schedule a viewing at Shadyside Apartments. 
What day would you like to make the booking for?
On Tuesday at 4 pm. 
Have you already paid the application fee for the apartment?
I don't remember. Also, I just got a call back from a company I'm applying for and I have a job interview on Tuesday at 4 pm. Can you see if the apartment is available for viewing at 6pm?
I am sorry, but there is no viewing available at your preferred time.
Can you try Wednesday at 4 pm then?
I am sorry, but there is no viewing available at your preferred time.
What about 6 pm? I really liked this apartment since it's close to downtown and a bunch of restaurants. 
Great, there is still a viewing available at that time. Would you like me to book it for you?
Yes, sounds great! 
Your apartment viewing has been successfuly scheduled. Please bring Proof of Income and SCHUFA certificate with you.
Ok. Now I have to prepare for the job interview so I can pay for the rent. 
Is there anything else that I can do for you?
No that will be all, thanks a lot! Bye!
Thank you and goodbye.
