If you have a brick & mortar location your first job is to generate foot traffic and people willing to come in and sniff at whatever it is you are selling. That achieved, your next job is to have the sales staff to be able to actually be sales staff and make the sale, close the deal, get it done, satisfy a customer so that they have no reason to go elsewhere. It's freakin high-end retail 101. Hell, it's general retail 101. I worked retail at higher end shops (not audio) for decades and customer service was always dealing with tire kickers, but being damn smart enough not to piss anyone off. Must be tough these days with much of the world buying online, and coming into a store just to fondle the gear and then go search online for the lowest price. It doesn't matter if a "demo" or listening session is not really a benefit for most purchases, you as a dealer do it as it is the right thing to do. Make the customer feel like the purchase is an elevating experience among fellow enthusiasts. If you can't close the sale enough of the time you deserve to go away. That said, must be tough to be selling audio gear these days when there is more snake oil and fallacies than ever before to deal with, and people have drank all the Kool Aid that contradicts electrical principles!!!!! :-)
