Good evening ! This is Mr . Smith in room 609 .   Good evening , Mr . Smith , What can I do for you ?   I'm going to Shanghai early tomorrow morning . So I would like to request an early morning call .   Yes , Mr . Smith , when would you like us to call you tomorrow morning ?   I have to be at the conference room of the Garden Hotel in Shanghai by 10 o'clock . I think it will take me three hours to get there . It means that I'll have to be on the road before 7 o'clock at the latest .   That's right .
