Can you find me a sushi restaurant?
Something near your house?
Yes, please, and well reviewed.
Mikuni is close to you and is popular, does that work?
Sure, can you make me a reservation for 3/31 at 5pm for 6 people?
Mikuni has no available reservations for that day. Want me to try another day?
Yeah, do they have any availability on 3/30 at 6pm?
They have a table, but for 2 people only.
That won't work. Can you find me a different sushi restaurant?
What about Blue Nami on Greenback?
That works, do they have a table available for 6 on 3/30 at 6pm?
No space on 3/30, they're too busy for a party that big.
Are there any tables 3/31 at 5pm?
Not at 5pm, but I they have space at 8pm.
That's too late.
I can do a table for 4 at 4pm. Is that too early?
That might work. Is it busy at that time?
Not usually. 
Okay, yes. Please book the table for 4pm.
Reserving you a table for Blue Nami at 4pm for 6 people. Give them your name when you arrive.
