When customer X comes into the store and is in love with speaker Y that he read a glowing review of in publication Stereophile do I start lugging the box out to his car with my pocket full of cash?
No. I and quite a few other sleazy salespeople qualify the customers possibly misplaced lust for a possibly over hyped POS that got a great review. Often a more appropriate for room/equipment/listening preference product is available for the same if not lower price.
Is this 30 second redirection easier and more cost effective than reading hours of anonymous threads, purchasing without audition (at a great discount!), waiting, setting up, waiting for break-in, and only then realizing that this was not the right product for you?
When you go to Outback Steakhouse and ask the super-duper intelligent waiter for a recommendation on a meal that will satiate you for 8 hours you not only pay full price without hesitation,... you tip 10-15% for the honor of getting a medium steak when you ordered mid-rare and a 10 minute wait for a second Budweiser.
Go get good advice, a personalized demo, an in-home demo, from a knowledgeable salesperson on a product that you may keep and enjoy every day for 20 years and you beat him out of his commission and the store out of some of the profit that it uses for little things like electricity, wages, insurance, pest control, paper for the printer, etc.
Sure dealers get any number of different incentives to pay bills on time/early, buy in quantity, and demo entire lines of products. These huge sums of money keep them in the black too right?
Profit=good thing.
