Hello how may I help you? I need to order a pizza Great, I can get an order started for you. What would you like? A large pepperoni, olive, and mushroom pizza Unfortunately the topping "olives" is currently out of stock. Would you like to modify your item with a different set of toppings? How about pineapple? That topping is available. So you'd like one large pizza with pepperoni, mushroom, and pineapple, correct? Yes please Great, I've added this to your order. Would you like to add other items, or checkout? Checkout Completing your order... Done! It should be ready for pickup in approximately 20 mins. Great. Thanks!
