Hey assistant, order me a Energy Vanilla Drink of Starbucks
Sure, do you want it shipped to your location?
Yes. And let me know how long should I wait.
Placing the order and charged to your default payment method, it should take about 20 min to arrive on current traffic. Do you wish to order anything else?
Yes. I want to order a pizza.
Okay. I found you have Dominos, Little Caesars and Pizza Hut close to your location.
Which one is closer or will serve me faster?
From what I can see Pizza Hut will have your order faster at this moment, with up to 25min delivery.
I want to order from there then.
Okay, What do you wish to order from Pizza Hut?
I am not sure, which pizzas toppings do they have available?
On this location they have, Cheese, Pepperoni and Supreme they also allow you to make your own selection. Which one do you wish to select?
Do they have any deals available?
They do. At the moment you can order 2-topping for $7.99 and $5 dollar Pizza item if you order 2 or more items. Do you wish to order any of these deals instead?
No. I'll just go ahead and order a Cheese pizza.
Got it. What size do you want it? Large or Medium
Medium size.
Got it, how many of them do you wish to order?
Just one.
Got it, One Cheese Medium pizza. Do you want to add any additional item or sides?
