Well , sir . We are asking all our guests to wear a jacket and a tie in our restaurant .   Is that so ? I didn't know it . can I possibly borrow a jacket and a tie ?   I am sorry ; you can't borrow a jacket and a tie .   Then we'll return to the hotel and come back , will you change the appointment ?   Certainly , what time will you come back ?   At 7 , please .   How many in your party ?
