... Two Large Black Coffees, That's All!

Almost every day of my life, I say the phrase "Two Large Black Coffee's, ... That's All!" to an unknown person at a McDonalds drive through window. 40% of the time, I hear something like, "Do you want an apple pie with that?"
Recently, these unknown people have been identifying themselves by saying ... "Hello my name is Alicia, ... ".
Seriously Alicia? Two Large Black Coffee's, ... That's All!
