Hello, I need to order some food, and I was thinking of getting a pizza.
Hi, I can help you with that. Do you know where you want to order a pizza from?
I was thinking of ordering from Hounddog's Pizza.
Ok, can you confirm the city?
Yes, it is in Columbus, Ohio.
Got it, and what type of pizza do you want to order?
I want to order just one pizza. I would like to get it with pepperoni and onions.
Ok, you would like a pepperoni and onion pizza from Hounddog's. Do you know what size?
Umm, not really sure. Do you know what size is good for 3 people?
Let's see, it looks like for 3 people the best size to get is their 16 inch pizza.
Sounds good.
Great, it also looks like you have a choice of sauces. Do you know which one you want? 
I'm not sure, what are the choices?
The sauce choices available are Pesto, Joes, Original, Spicy, and Howlin' Hot.
I think spicy would be good.
Perfect. Is there anything else you need to order?
No, that will be it.
Ok, let me confirm. You would like 1 18 inch pizza with pepperoni and onion, from Hounddog's Pizza located in Columbus, Ohio. You also would like the Spicy Sauce.
That is correct. Please place the order.
Ok, your order has been placed. The pizza will be ready for pick up in 25 minutes. I have sent a receipt to your mobile phone via text message. Is there anything else I can help you with?
Nope, that will be it. Thanks for your assistance.
No problem. Have a good day!
