Hey, can you order me a pizza from Papa John's? I'm having a buddy over tonight, and I think we both want pizza.
Sure! What kind of pizza do you want?
Well, I'm actually not really sure. He likes pizza with sausage and ham and pepperoni. But you know me, I just like the classic cheese.
You could just order half with his toppings and half cheese.
Oh yeah, you're right. I was thinking that I might have to order two pizzas, but one split down the middle would be perfect. So half with sausage, ham, and pepperoni, and half with cheese.
You could just get meat lovers for your friend's half, it would be easier to order and they would add bacon.
Oh yeah, that does seem easier. The more meat, the better.
What size did you want to get? 
I think a large would be good.
Are you sure about that? I know you can put away some pizza. They have extra larges, too.
Yeah, might as well get an extra large! I love leftover pizza anyways.
And you want regular crust, right? No thin crust or stuffed crust?
Actually, I do love a good stuffed crust.
So, an extra large, stuffed crust, half meat lovers and half extra cheese?
Yeah, that sounds about right!
I'm looking on the website and they actually have a deal where you can get two medium pizzas for only $6.99 each. Did you want to do that instead?
Actually, I saw something once that said that you get more pizza in a large pizza than in two medium pizzas. Something about area or something, you know I was never good at math. So I'll just stick with the extra large.
Okay! I'll order it right not and get the receipt sent to your phone in a text.
Sounds good!
Your order is complete, so I can go pick it up for you in about 25 minutes.
