Based on 40 years of experience, Hi Fi dealers often tend to be kind of rude, but once you make friends with them, things often change.
I live in Milan, Italy, and I must say that the old Hi Fi dealers in my city (this was in the Eighties and Nineties - they have all closed since), where terribly rude, with very few exceptions.
I remember parking a brand new Porsche in front of a well-known dealer downtown Milan and, when I asked them if I could audtion a specific product, which I knew they had on display, they told mw to come back another day (the store was empty).
They lost a good sale.
