My most successful sale was one where I had taken over a customer from another salesperson who had to leave suddenly. I immediately contacted the person, and let them know the situation. I knew that my colleague was having a difficult time getting the client to commit to the purchase of a large motor home. Part of it was circumstantial, but when I was given the opportunity to take over the sale, I was able to give the customer some reflection time, and was ultimately able to close the sale.
