Hey, I need to make a dinner reservation for Friday. I want to do Thai food, I'm want one of the more exclusive spots.
Okay, I can make the reservation for you. 
Can you check Langbaan in Portland and see if they have a table?
Sure. How many people do you need to seat?
Five people. 7:30 pm would be ideal.
Okay I'm checking now and they don't have any reservations available for five weeks.
Oh wow, really? Okay well I'll pick something else. 
I can try and search by availability. 
I just want noodles or dumplings. 
What about Han Oak?
Oh yes, I love their appetizers. 
Do you still want the reservation for 7:30?
Yes! 
Okay so the good news is that they do have some tables open on Friday but not at the time you want.
What time is their earliest open table?
6:30 pm
That's fine. Can they seat five at that time?
Yes, they can. 
Okay go ahead and book that table. 
All done. You should get an e-mail confirmation soon and it has the address and everything.
Looks like it just came through. Thanks! 
You got it. Talk to you in a bit.
