Hi, I would like to order pizza please.
Sure, which pizza place?
Jet's pizza please.
Okay, what can I order for you?
I would like a pepperoni and mushroom pizza please.
Okay, what size?
Just a medium size.
Oh, I'm sorry. They are out of mushroom.
Oh, in that case, how about pepperoni and bell peppers?
Yes, that's fine. They do have bell peppers.
Good. 
Would you like hand tossed or thin crust?
Thin crust sounds good.
Okay, so that's a medium pizza with pepperoni and bell peppers on thin crust?
Yes, that's good.
Is there anything else?
No just that for today.
Okay, your pizza will be ready for pick up in 25 minutes.
Okay, great!
I will send the receipt to your email address.
