Sales person or sales professional?

There are far too many people in sales jobs who are sales people; they’re not sales professionals. How can you tell the difference? There are lots of ways but one of them is in how somebody who works in sales, treats someone else in sales when they are the customer and are being sold to. Disappointingly, in those circumstances, the customer will very often treat the seller with the same lack of respect they themselves experience when they are selling. So which one are you – sales person or sales professional?
