Hello there, I would like to order a pizza.
Hello, how can I help you?
I would like to order a large Pepperoni Pizza from Pizza Hut.
Great, I can help you with that.
Thanks!
How many toppings do you want?
I would like to have two toppings for the order.
Sure, what toppings do you need?
I would like to have olives and spinach.
Great, let me check it for you.
Thank you. 
Sorry, there are no more olives.
That's fine, what else is available?
There are meatballs and other veggies.
Let's substitute meatballs for that.
I will do that right away.
What else do they have there?
They have plenty of things but only two toppings per large pizza.
Awesome how long will the order take?
The pizza order is complete and the pizzas will be ready for pickup in about 25 minutes.
Thank you!
You are welcome.
