Yes, What kind of pizza were you thinking of? 
That's a tough question. 
Right?
okay, I will get the speciality Chicken BBQ.
What size? 
Medium, please.
Do you want anything else with your pizza? 
Yes, can I get a side order of whole milk? 
Good choice! Alright I will place your order. 
Thanks! 
Hey, sorry to inform you but ABC'S is out of chicken BBQ today. Would like to get something else?
Oh, no! Okay let me get a usual one. 
Any extra toppings? 
yes, olives and pesto.
Sure, I will let them know. 
Thank you and please get something for yourself as well. 
Oh thanks, I sure will. 
Cool.
