When someone notices that you are the right person to help them, here is what might often times be present :
1)You're asking questions and they feel understood.
2) You're listening to them and looking them in the eye.
3) You're not putting words in their mouth.
4)You're picking up on their body language and acting accordingly.
This often times can't be taught, but makes the world of difference!
When is the last time someone treated you with respect and made the sale easy for you ?
