To the OP, your entire experience is completely on those two sales guys. Because they're not here to give another side of the story, we don't know what really transpired at that moment or what kind of vibe, maybe you might have given off when you were talking to them.
I've been a sales professional, a pretty well paid one and a fairly nice guy and having an abundance of experience, I could/can accurately shortcut with my eyes and mostly never get it wrong- and if I did, I deserved the loss that came with it because I probably did something wrong myself.
When anyone brings up these subjects about being rejected at the audio salon, it immediately turns into an us against them kind of thing here in the forums where the customer is virtuous and the salesman was an a*shole. That, unfortunately is often true because there's no real standard on manners anymore, the workforce in the 21st century often leaves much to be desired or completely void of face to face relationship building skills. You have to understand, whether we like it or not, these paid for brick and mortar establishments cost a lot of money to startup, run, turn the lights on and buy the inventory- more than ever before in modern history- and so on and so on. We all know exactly what we've all done. I've absolutely done it once or twice. There are very few of us here who didn't walk into an audio shop to hear a set of hot or well reviewed speakers or a preamp.. just so we can free ourselves to go online and buy it cheaper someplace else from someone who doesn't have the investment, didn't put in the time and experience that the brick and mortar guy does.
You say you were willing to buy that day, I don't think you're lying, but everyone who walks through the door tells that bullsh*t story, I guarantee that's true.
So I cut these guys a little slack and my suggestion to you and anyone else who's reading this, don't break balls if you're not serious and don't use someone else's time & money to do it because that's what you're doing if you use the audio salon and their time to kick the tires and ultimately buy it or (most often) not buy it elsewhere.
