In the world of show business and live entertainment, every act has an “opening.”
Most people think it’s the first words that come out of the actors’ mouths, but it’s more than that. It’s the moment the audience sees the actors walking onto the stage. It’s how they are dressed, how they make eye contact with the audience, the anticipation they create, and more. So, when the actors speak their opening lines, it is actually the end of the opening.
It’s the same in business. You call the customer service hotline.
