Hello! Welcome to McDonald's. What would you like to order?
I wanted to order 6 Chicken cheese sandwiches and 3 large cokes and 2 large fries and a Oreo Macflurry
Awesome! You have a great taste.
thanks
Great! Is there anything else that you'd like to order?
No I wanted to reduce the number of chicken cheese sandwich to 4
Sure, not a problem. Will that be all?
yes
Great! Please pay the bill at the next window. Hope to see you again. Bye.
