Hey there! Welcome to McDonalds.
Hello
What would you like to order today?
Can I get a large Big Mac meal with regular coke?
Sure! Would you like to have something with it?
Sorry about that, can you change the meal size to medium please?
Of course, I'll make the changes in the order. Would there be anything else you'd like to add up to your order?
No, that is all.
Perfect! Your order for 1 medium big mac with a regular coke is ready, kindly proceed with the payment at the next window.
Thank you, see you around
