Have you ever been turned off by an Arrogant Dealer? Thoughts

Yes and you just move on.

Yes. I think everyone eventually runs into some arrogant jerk. Although as my career moved on, it happened less and less. Audio folks can typically figure out what you can afford. Some of them are only in it to make money, they are not there because they love the music and high hi. So they will make a call and write you off, right or wrong. Although if they are disingenuous, I'll write them off and not buy there. 
 

There's a guy in Chicagoland. Quintessence audio. 

He was very accommodating demoing equipment for me. I didn't buy and felt no pressure. If I find something I really want, I won't hesitate to buy from him. Highly recommended! 
 

When I go to dealers it's on my days off, so I'm in my shorts and scruffy gear.

They dismiss me as though I can't afford anything in their shop.

There are those that 'get it'....and those that don't, and may never....

Local ACE hdwr. relocated...new shop center, don't know me from the mulch in the outside bed with typ. plant...

'Hey, you're a Stilhs' dealer! Kewl...." Got treated with respect and good 'tude since I pushed the door....cruised the display, no pressure....

Came back w/my foreman..."Which?"  Needed some hardware, bought all they had, asked if they could order a case of same.

Did it.  Didn't know me from a wheel stop.

Foreman came in & picked that case. I came back separately and dropped $ on a mid-level saw and some this 'n that.  800$ bang to start their day.

Friendly and good cheer at all times...and knowing enough to get out of the way while the decisions were made....even if elsewhere....

No, not audio, but smart sales....let 'm look, costs nothing but an eye....Serious will ask serious queries, perhaps pull the trigger.

It's like fly fishing, although I don't....  Bait is overhead....

If they come in asking for Nirvana, it ought to be obvious within a minute what's in the mind of the 'client'..

If not...hire a new sales stiff.  If it's your brother-in-law....shoot self.

On-Line?  Do your research like you'd buy a house.  If it stinks, don't get hosed with it as well.  PayPal ain't perfect, but neither are we.  Gird thy loins....

If I'm only preaching @ the bored choir....well...

Shut Up & SING....fer G's sake....
