This is why you hire service and trades people with a known reputation and a long, positive review history. Or intimate word of mouth.
I’d trust our HVAC guy in the house alone with my wife because I trust him. More to the point, he carries all sorts of tools other than guns that would aid him in being a lethal a-hole if he was an a-hole in the first place. But he’s only in the house because I know he’s not an a-hole in the first place. Also, my wife is pretty quick on the draw and has highly sensitive a-hole radar.
Agreed, I am okay with an armed service tech around my wife.
