No, I do not think there has ever been any doubt in my mind about the mood of a coworker upon their arrival at work. I worked with a woman once who explained to me that she was a Gemini and if she ever came to work not talking or grumpy, it was the other twin. However, her mood would lighten by the end of the day.
Nonverbal communication is the single most powerful form of communication. With that in mind, discuss how important nonverbal communications are when dealing with customers. Nonverbal communication is extremely important. It can cause someone to get the wrong impression and make him or her feel extremely uncomfortable. I can remember going to my second job and feeling exhausted, I wasn’t upset but because I wasn’t my normal chipper self, I was perceived as being angry. I smiled or talked only if someone had something to say to me. My mind was on going home and getting a hot bath and getting into bed. My shoulders were slumped and I had to keep visiting the restroom to wash my face and try to talk myself out of not leaving the crew short-handed. Boy was that hard.
