I'm taking my family out to sushi. Can you book a reservation for me?
Okay, which restaurant?
Kitzmo Sushi
For today?
Yes, April fifth.
Okay, what time?
six.
how many people?
fifteen
It says the largest parties they accept are ten.
Can we split us up seven and eight? Make sure they are both for six pm though.
So, it looks like they only have space for a reservation of four or less people at that time. Should I check thirty minutes either way or do you just want me to try a different restaurant?
Well, sounds like a different restaurant needs to be selected. 
I agree.
Okay, Sushi Time. Do they have availability that I am looking for?
One moment and I'll check.
Go ahead.
Yes! I can book your entire party of fifteen together
Great! Thank you.
Glad to help.
