Hi, I need to have my car serviced at the dealership. 
I can help you with that. What kind of service do you want?
The door lock on the front passenger doesn't consistently work. Sometimes it is locked and sometimes it is not.
What's your car model and year?
It's a BMW X3 2015.
Would tomorrow 8 am work for you?
No, I would prefer to have my car serviced today.
I know we are fully booked for today but let me check the schedule and see if anyone cancelled.
Thanks.
There's a slot at 2 pm today that just opened 5 minutes ago. Would you like that?
Yes. I would prefer that my car door be fixed as soon as possible. 
The initial inspection for the service costs $300. Additional costs may be incurred depending on what the technicians see. 
That's expensive but ok. 
So to summarize, your BMW X3 2015 is scheduled to be serviced today at 2 pm. The task is to fix the front passenger door lock. Initial inspection costs $300, additional costs may be added depending on findings.
Sounds good. 
Do you want a loaner car for today?
Not really. How long does it usually take?
Inspection is only about 30 minutes however, it is difficult to say how long the actual repair would be. 
Ok, i'll just decide then when I get there if I would want a loaner car. 
No problem. 
Thanks.
Is there anything else you need?
