When you go to hotel
Book: 하룻밤에 얼마예요? (How much is it a night?)
Real: 하루에 or 1박에 얼마예요?
*하룻밤에 얼마?? This phrase is kind of .... question...
;; when men buy a woman for a night as usual...
And I think most of people will look the price up before they go to the hotel.. I think we don't need to know this kind of phrase
