Yeah but remember like mail drops, telesales is a matter of numbers. We know that the success ratio is going to be shit but the labour is cheap and the gems are easily minable. However if you're going to "sell a grand piano" your margin is higher and thus you can employ someone who has better sales techniques. I agree that it is the same game as A/B techniques but there are degrees of viciousness at play here and the classic "piano salesman" is well towards the devious end.
