Hi, I would like to reserve a table for dinner tomorrow evening.
Sure, what is your restaurant preference?
I would like to reserve at Ken Stewart's Grille
Certainly! What are some of the specifics that you would like included with your reservation?
I would like an outdoor table for 4, high chair for the baby and we would like to be there by 6pm
Sure let me schedule that for you.
Thanks!
I'm very sorry, but Ken Stewart's Grille does not have an outdoor table available tomorrow night
Oh no, that's too bad
Do you have a second option that you would like to try? 
Yes, try the Dante Restaurant, please.
Okay, they have openings available, but not until after 8pm
Whatever?? I'm afraid that will be too late for us
I'm sorry about the inconvenience. 
So no chance of getting in there at 7pm?
No, that's not available 
Okay, I think I'll just cancel the reservation since they don't have the time slot that I want. 
Okay, let me know if I can be of further assistance to you
Okay, thanks for your time!
No problem!
