As I was reading your post, Barbara Striesand came to my mind. One of the guys I worked with was so excited to do security at her concert, so afterwards, he walked up to her and said what an honor it was to met her. She asked him if he liked working here (Capital Center) and he said yes. She said then if you want to keep your job, I suggest you not continue to speak to me. He never listened to her again.
Years later, my husband was doing security at Clinton’s inauguration and stopped her to verify if she could enter. She lowered her glasses and said excuse me and pushed her way by, being a real snippy snob about it. Now when he sees her on TV, he cringes.
