The Comcast article is infuriating.
The "surprise" install charge is likely due to the customer wanting new lines, and "I don't want wires on the outside of my house". Well, around the outside is commonly the easiest way. You want somehing done the hard way, it stops being free. People hear "free installation" and think their entire house is getting rewired, inside the walls, or whatever other stupid ideas they have, and they won't get billed for it. I routinely get customers who want Ethernet lines run everywhere for computers and game systems, and they don't understand why that isn't free with their modem installation.
Stealing his tools was bad enough, but threatening someone's LIFE over cable tv? Insanity. I don't believe for a second that she pointed the gun in the air, no one does that. I have no idea how she thought that would go well for her, if she was even thinking at all.
No, I don't work for Comcast, btw.
