Not all people are good communicators.
And burn out from decades (depending on how long the business has been around) of entertaining tire kickers does tend to be a thing, you know......
When Goo Systems was principally connected to the Tri-Art offices, I was the phone guy for almost 5 years straight.
At the end, I was basically curled up into the fetal position, under the desk ...and incapable of taking even one more phone call. With at least 50 waiting messages in the system.
Each one of them wanting me to talk home theater with them, for hours, if not days. Each.
Each wanting to drain my brain on any and all parts of acoustics, video screen technology, human hearing, human vision, projection technology, noise control, room isolation, room set up, equipment choices, cable choices, and so on.
We ended up with someone else on the phone, in fairly short order... as I was burned out and it took years before I would touch another phone again.
