Whats it mean when a man winks at a woman?
A customer comes into my work and everytime he sees me there he will wink at me and smile. This morning I took my boyfriend there to get breakfast, and the customer came in and winked, smiled, and would turn around and keep looking at me? Of course I smiled when he did it. So what does it mean and am I wrong for smiling back at him when he does it?
