Who is the WORST Audio Shop?

Here is one in Winnipeg Manitoba Canada.
Creative Audio. Naim / Martin Logan / Regga dealer.
Walked into the store dressed in Jeans and a cap and a Norton Motorcycle t shirt..I was pretty well barricaded at the front door till I explained what I was looking for. I told him that I was interested in hearing what high end Naim sounded like compared to my current set up. He said your best to make an appointment. There was not one person in his shop. I explained I had $15k burring a hole in my pocket. He mumbled something like ya right. I told him never judge a book by its cover and left. He watched me drive away in my brand new F 250 Super Duty. I headed over to Advance Electronics  and picked up a Mac C2300 and MA2102 Tube set up. Some sales peoples arrogance astounds me.

I've had a few bad experiences in shops through the years, never went back to any of them.

I think that's the best course of action, regardless of the type of shop.

Back  in 70's I was selling Audio for a big dealer.
Scruffy looking old guy walked in, walked like he was drunk .
Nobody seemed to want to wait on him, I did and in 10 minutes I made a 5K
sale(like 25K today) to the owner of a  truck line who filled in for
a sick guy and had just driven 800 miles non-stop and was 50 miles from home .

Another vote for Sound by Singer in NYC. Andy singer is an arrogant pr**k. I don't know how he stays in business.

Cleeds...

Not returning to a rude retailer is indeed the best course of action but letting them know your experience is necessary. 

While unrelated to audio, I had an experience with a "premium" car dealer that was so over-the-top miserable that when I bought another make later that afternoon I returned to the former with a copy of my bill of sale, leaving it on the GM's desk.
