A : "I would like to have Set A. Can I add an egg (side dish)?"
Staff : "The set very big. Cannot put the egg."
B : "Give me Spicy Tomato Pasta. Don't want set. Can I add an egg?"
Staff : "The pasta a lot. Later the eggs will drop."
A & B thinking why can't you just put the eggs on a side plate?
The staff must have been taught A is A and B is B.
No wonder they have issues with productivity.
