I'd like to order pizza for my lunch meeting today.
OK - which place?
Let's order from We the Pizza. You know that's my favorite.
Sounds good. What kind do you want today?
Let's do the simple cheese pie, with mushrooms and artichokes.
OK - they have two sizes. Do you want medium or large?
How much more is the large?
Just $2 more.
Oh, yeah, let's do the large and then we'll have plenty.
Great. So that's a large simple cheese pie with mushrooms and red onions.
Yes, that's right.
Looks like they are out of artichokes today. Do you want something else?
Let's do spinach instead.
Great. Hang on just a sec. OK, the order is submitted and will be ready for pickup in 25 minutes.
Did you get a receipt for my expense account?
Yes, they'll text a receipt to your phone.
Great.
Do you need anything else?
No, that should do it. 
I can pick it up if you want.
Sounds good, and you can just bring it in. Don't worry about interrupting. It's a casual lunch meeting.
OK. Will do.
