During my many sales trainings, there is one item under the module of Sales Presentation where I touched on hand shakes that sales people should avoid should they meet up with the client for the first time. They are :
1. The Hand Glider
2. The Finger Tip; and
3. The Soft Touch
Anyone of the above handshakes could send off a wrong signal to the prospect of your desire to do business with him/her.
However, besides the three mentioned, there are more for sales people to take notice of.
