Here’s a quick tip … how can you tell that a person is genuine?
Look at their body language when you are first introduced. They will step forward and offer a firm handshake combined with a warm smile. Their head might be tilted just a bit and often eyebrows arched. They might even bow!
(Can you see their bottom teeth when they smile? If you can … it is most likely a fake smile.)
Now you need to be genuine as well. Put down your smart phone, smile and lean forward if you are sitting. They are now the MOST IMPORTANT person in the world, so give them your full attention.
