In this case the "little hifi shop" was Tweeter/Sound Advice. Sound Advice was a Florida company, tons of stores, that was bought out by Tweeter, which was more of a nationwide US company.
My buddy worked there starting with Sound Advice. One day visiting him he was in the back eating lunch, and I stopped and stared at the large "Drug Free Workplace" sign, which gave us both a laugh, as the company was originally started out of Ft. Lauderdale FL to launder drug money. Oh the irony...
