Ok, who lived in South Florida in the 80s, and remembers the ad, I think it was for Sound Advice, with the haughty salesman going, "Really sir, that's a multiplex demodulator!"
Here’s my 1990’s Best Buy story (happened more than once):
Me: I’m returning this electronic device. It doesn’t work. And I’m still within the return period.
Best Buy employee: You must have broken it. No refund.
Me: What? I demand to see the manager.
Best Buy manager: You must have broken it. No refund.
(Contrast that with Amazon’s return policy today. No muss. No fuss.)
I do!
Do you remember Luskin's? They were an East Coast electronics chain that would have HUGE clearance sales where they would unload last year's models for super cheap.
I worked for Radio Shack at the time and Luskin's was just up the road. People would buy their receivers and speakers there and come to us for the cables. Was always amazed at how cheap their stuff was.
