I'd like to see something that highlights the difference between "technical sales" and "retail sales", or "sales in general". (I'm using the quotes because I'm not quite sure of the terminology, but I think that gets the general idea across.) Selling, say, a car to the general public is very different from selling a specific and highly technical product to financial engineers. Both "technical salespeople" and "retail sales" seem to have a lot of trouble understanding the differences in techniques and emphasis.
