As others have stated, it's hard to know what really went down when the OP visited that shop. I'd love to say I'm surprised to hear about his negative experience with a high-end retailer, but I'd be lying if I did. That said, we're only hearing one side of the story.
I haven't personally set foot in a brick-and-mortar audio shop in a very long time. None of the gear I was interested in for my latest system was available locally, so - for the first time ever - I bought everything sight unseen and sound unheard. Risky, to be sure, but I relied on word-of-mouth recommendations, my own research, and remote dealers with whom I spoke at length and who earned my trust. Luckily, it all worked out very well, but it could just as easily have gone south.
While building my current system, I did run into one local retailer who really put me off. They were the only dealer in the area selling a storied British speaker line that interested me. I contacted them about auditioning a particular pair of the brand's speakers, and they told me they didn't have that model in the store. Since it's one of the brand's most popular and celebrated models, that was a bit surprising.
I asked how I could audition the speakers before purchasing them, and they told me it wouldn't be possible - all of their customers simply buy them without hearing them first. I ended up finding a similar used model for sale online and purchased those instead.
A few weeks later, I received an email from the dealer stating that there was going to be a price increase on the speakers I'd inquired about, but that he could get me a pair at the current price if I ordered quickly. I politely replied that I had purchased a similar pair elsewhere, but thanked him for reaching out.
He responded by asking if I would be willing to share why I hadn't purchased the speakers from him, as they wanted to use the feedback as a learning experience. I explained that I wasn't prepared to buy speakers at that price point without listening to them first, and that they had made no real effort to accommodate my request for an audition.
That clearly annoyed him. He sent me a very nasty reply criticizing my purchase and disparaging the speaker brand he sells, claiming he could have sold me a better pair of speakers for less money. So not only is he a terrible salesman (and, as it turns out, the owner of the shop), but he's also an awful representative for the brand. Needless to say, they'll never see a dime of my money.
