I think salespersons should be looking for a verbal commitment to ask questions and they should only sell to what your customers tell you. No one cares about the salesperson, you can be whoever you want, all that matter is your presentation as it all about the performance. Short presentations are best in my opinion because if you go on a monologue then your clients are not really listening. Good salespersons look for a way to make a connection with their customer, and build a conversation based on trust.
