> One of the reasons they have the loud ding is to alert an associate working several aisles there is a customer there so they can go assist them.

I sincerely hope they don't believe that's what customers are experiencing, though. And I've never had an HD employee zip on over to help me out when I've been browsing electrical parts. I have, however, started being a little immature and occasionally flip off the camera when it dings at me. Such a rebel I am ;-)
