The same experience at Arlington Heights
(Chicago area) GC. I went to buy a mic preamp. I was standing there for about 30 minutes looking at one sales person after the other waiting for help. When I started to look for one by myself among the boxed products on the floor, a salesman approached me -if not confronted me- asking "can I help you ?". He was not friendly at all; he looked annoyed. I bought the preamp on that day from them, but will never go back to that store again.

I have had much better experience at Cincinnati Mars when I was living in that area.
