Taking advantage of my new position

Robin walks past them inside the building. There were stairs and an elevator to go upstairs. He observed for a while. Then decided to take the stairs. Going up he went to the twentieth floor as mentioned By Chris where he will meet the owner of the Walter group. 

While going straight through the hall he met up with a man. 'He seemed to be a staff here. ''  Excuse me can you help me ?'' Robin asked tapping on the man's shoulder. '' Ah yes, what help do you need? ''. 

'' I am looking for the owner's office can you show me on which floor it is? ''. '' Owner? oh you mean the one in charge here? ''. '' Yes, do you know where he is? I am not that good with business terms so I don't know. Will you take me there ? '' pleads Robin. 

'' Sure but before that, I need to call the person in charge you can't go in there without an appointment ''' asserts the man taking out the phone from his pocket. '' Ah yes, you can do that tell my name Robin '''.
