Bullshit. You’re confusing a retail sales with a real sales professional. A REAL salesperson identifies a need, proposes a solution, and creates a value to the customer equal to or greater than the price of that product. Someone who convinces a customer to buy what makes him the most commission is not a salesman, they are a lizard.
I’ll take guys like you every day over someone who doesn’t know what they want. Believe it or not, guys like you are the easiest sale. You think you’re a tough negotiator, but the salesman will make you agree that something is the right product, fight you on price for 20 to 25 minutes, then give you a bone. You go home thinking you got the best of him, but as long as you have his product in your trunk, he could give a shit if he sold it for a discount off of list price.
