Earlier quoted context omitted.
As a Tesla investor, I'm very curious what the conversion rate is of Home Depot/Big Box customers vs Tesla stores. My guess would be it's much higher in Tesla stores. No one likes being bothered at Home Depot by sales staff when they've just popped in for a part.
Maybe this would go too far into the "uncanny valley", but why not have teleconferencing sales people? Eg have a terminal near the solar products where you can hit a button and immediately be connected to a remote sales rep. This way you can cut down the sales reps to, say 0.2 per store. And you never talk to one unless you want to either.
I think the point of intrusive, unsolicited salesmanship is to convince people to look into products that they would otherwise ignore. People go to home depot to buy hardware, not to meet with salespeople.
