If you think it's a sales pitch, then the tech is doing it wrong.
And if the tech never made a single offer then you may never know the things they carry on the van or the services they can provide.
Personally, I think it's ridiculous to go buy a TV because of the phenomenal picture that sounds like an AM radio.
I think it's silly to pay for fast internet in some homes, in some parts of the home, because of WiFi falloff and weak signal strength to NOT explore Mesh Routers.
I think it's stupid to plug your electronics into power strips instead of Surge Protectors.
I think it's silly to mount a TV and NOT use a kit to hide the wires.
I think Doorbell cameras are becoming more and more of a necessity and less of a novelty.
But, that's just me
