Hello, I need to set a viewing for North Hill Apartments on Thursday at 7pm.
Could you give me your name, please?
Yes, John.
I am sorry, but there is no viewing available at your preferred time.
Ok can we try on Friday?
Great, there is still a viewing available at that time. Would you like me to book it for you?
Oh wait, I just remembered I have wedding for an old friend on that day. Can we try on Saturday?
Great, there is still a viewing available at that time. Would you like me to book it for you?
Yes please, but I don't remember paying any application fee because I have seen so many.
I have booked your appointment. Please make sure to bring your passport, SCHUFA certificate, and have funds available if needed for an application fee. 
Ok great and I can't wait to see this wedding on the private island!
Sounds great, have fun! Do you need any more assistance?
That is all thanks a million.
Thank you.
