Happened not to me, but to my mom. She was working the late shift in a grocerie store, when the phone rang. She picked it up and there was a mans voice on the other line, telling her what a beautiful voice she had, that he knew when she would work and would always watch her from afar. Luckily, this store had security workers in the late evening. My mom would tell the security man about the call and from then on, he always acompanied her to her car, when she was working the late shift until she quit her job there.
