One Question at a Japanese Register Decides Whether Your Food Comes in a Bag or on a Tray

Why this phrase

Kofuku is the customer at a fast food counter; Hana is the staff. She fires the question at full speed: the standard burger chain wording is the honorific form asking whether you will be eating inside the store. Kofuku freezes. Replayed slowly, the answer is two words. For takeout he says the negation plus the phrase; to eat in it is a short yes plus the location word. The one thing to actually train the ear on is the honorific verb, because at a cafe or a bakery the same question usually opens with the this place word instead of the inside the store word, and it means exactly the same thing. Keep the money claim narrow and honest: at the big burger chains eat in and takeout have been a single tax inclusive price for years, so the answer there costs nothing, but at a konbini or a Starbucks takeout is taxed at eight percent against ten percent for eating in, so the answer really does change the total. Two natural notes worth a line: when you initiate rather than answer, natives usually drop the copula and let the trailing particle hang; and never use the honorific version about yourself, that is the staff's word for your action.
