Hi, I'd like to place an order for pick-up from Twins Pizza please.
Sure, what can I get for you?
I would like a large pizza with sausage, green olives and onions.
any breads or salads?
Yes, I would like a medium greek salad and an order of garlic bread.
Ok, that's a large pizza with sausage, green olives, and onions, a medium greek salad, and an order of garlic bread?
Yes, that will do it, thank you.
Wait, they don't have all the items for the greek salad.
That's a bummer, how about a garden salad instead?
Let me check.
ok, great. 
It looks like they can make you a garden salad.
Ok, that is a good substitution. 
Ok, so let me confirm your order: you had a large pizza with green olives, sausage, and onions, a garden salad, and garlic bread.
Yes, that's it.
Ok, do they the name on the order?
Yes, Amy Andrews, 555-1212, and the card info is stored on the app.
Ok, yes, I see it there. 
Thanks so much, this will really help.
Ok, Amy, your order is placed and will be ready in 25 minutes.
