I need you to reserve a place for dinner?
What time and day? 
Book it for 03/10 at 5PM for 3 people.
Where would you like to eat?
At the Ranch.
I've called The Ranch. It is unavailable for 03/10 at that time. Can the meal be later?
No. Try the Hobbit.
They have availabilities that day but not at 5.
What time slots do they have?
Everything until 6:30 is taken.
Then, do 7.
To confirm, you want me to make a reservation for 3 people at 7:00PM.
Yes.
I've placed the reservation.
Remember to add it to my calendar. 
Of course. Would you like a reminder the day of.
Yes.
I've added it to your calendar and set a reminder.
Thank you.
You're welcome.
