Quite Frankly, I didn't know what “Shark Tank” was until I read this question you posted. I looked up a clip of this show and realized why they call it Shark Tank. Big powerful influential people having the last say concerning who they will keep and who they will throw back. Who they will intimidate will be the ones they eat and the ones that can swim pass them may come out alive and on top or a bit wounded but survive.
If I had the opportunity to appear on Shark Tank, the idea I would pitch to the sharks would be, starting up a business that would end up in a franchise. This would be a personal training company. Training different business employees on greeting others with personality, manners and having a quality customer service. Some say, you are either born with a personality or don’t have one. I believe personality can be taught.
An example: Have you ever approached a drive-thru and heard the person on the other end of the speaker sounding like a robot or sounding like their job was the last place they wanted to be? This poor attitude can rub off on the customer. Depending on the severity of the attitude this can cause a domino effect. The customer will not want to return, plus the consumer will be more likely to relay their experience to family and friends. Positive over rules Negative. Plus working with negative people can be contagious throughout a business so why not spread positive healthy germs.
A smiling shark doesn't bite like an angry shark.
