How to get a man to see you and not as a mutal friends sister?

Im in my early 50s. So is the man I am interested in. Only time I see him is at a place of employment. Although he and I grew up in the same town. I’m there as a customer… a few times his coworkers have asked who I am. He always replies its Tom’s sister. This man and my brother went to his school together 40 years ago. Although they are social acquaintances and have a few friends in common. This guy and my brother are definitely not friends…. how do I get him to see me for me and NOT my brother’s sister… please keep your replies, respectful. Nothing sexual.
