I'm hungry. I'd like to get a pizza from Stuft Pizza.
What kind of pizza would you like?
I want to get the Hawaiian Delite, but with Italian sausage instead of ham.
What size pizza would you like?
Medium, please.
Thick crust or thin crust?
Thin crust, please.
OK, will that complete your order?
Yes, please call it in.
I'm on the line with them, and they said that they're out of Italian sausage, and can only put ham on the Hawaiian Delite.
In that case, I'll get a medium Everything pizza with a thick crust.
I'll let them know you changed your order.
Great.
OK, they just let me know that they also don't have bacon bits.
Since they don't have 2 items that are supposed to be on the Everything, ask them if they'll give me a discount on it.
OK, they're willing to give you $1 off. 
That's fine. Please place the order.
Just to confirm, you're ordering a medium Everything pizza, thick crust, with $1 off.
That's correct. 
Pickup or delivery?
Pickup, please.
Do you want to charge it to your account, or will you pay for it upon pickup?
Please have it charged to my account.
OK. The total is $16.99. The receipt will be sent to your cell phone via text message.
Fine. When will it be ready?
That completes your order. The pizza will be ready for pickup in about 25 minutes.
