"Then you've come to the right place! My name is John, and you are? What about the [product] do you like?" And continue with sales process. Do NOT assume that customers know what they want. Prime Example: Dec 31st of 2008, I had a customer come in looking to buy a Regular Cab Silverado 1500 Gas Engine. He ended up driving out in a Crew Cab Silverado 2500HD deisel. The customer THOUGHT he knew what he wanted, but in reality had no idea. People will buy the sizzle not the steak. That was the last 2500 HD in our inventory, and it had a 500 bonus if you sold it. I made it sound like such a great deal that it would be irresponsible for him not to take it. He loves his new truck and has already sent me two referrals.
