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

Yes.

Luke Manley pissed me off so much in a conversation many years ago that I (regrettably) sold a pair of his Tiny Tots immediately afterwards.  
 

Not so much so, however, that I held onto the MB125s.

Yes … Arrogant Dealers who sign up to audio forums and attempt to throw their weight around with threats of legal action against forum members , Never goes down well.

I've never had any problems with e-commerce.  I have purchased McIntosh and Klipsch from Crutchfield and Music Direct and amps from Carydirect.  Each kindly answered all my questions and offered suggestions.  I also received thank you notes for my purchases.  My experience with bricks and mortar (BM) dealers has been nowhere as satisfying.  They will go unnamed here, but these jerks won't return phone calls or respond to email.  I wanted to buy a Mac MC275 amp and the POCs finally got back to me after I contacted McIntosh directly.  By then, I went ahead and purchased a comparable Cary tube amp and have been satisfied.  The BM make their money in home theater installs not sales.  Manufacturers know this, so they should consider e-commerce or direct sales.  The bricks and mortar dealers should just get out of the retail business altogether and focus on their precious installations.
