"turns out that customers respond well to a 'no BS' approach."
'tis true! 'tis true! The more high pressure (or, for that mattter, disinterested) sales tactics I get, the faster I run away. And if a salesperson should actually tell me (gasp!) "not to pay for differences I couldn't hear, and use the difference to buy more music," I would follow them around like a puppy. It's no wonder you were "top selling guy by far."
I marvel that more salepeople don't understand that honesty creates a satisfied customer who returns and, in the long run, spends more money than the customer "pressured" into a big sale who ends up dissatisfied.
