Comcast repairman doesn't give a damn that cars are sliding off the road to avoid his truck

It would not surprise me if there wasn’t an implicit or even explicit discouragement for safety. I know at my old job in the OR delaying the room for any reason was a BAD THING, and if you said it was for safety issues either they would try to convince you that it didn’t apply, or censure you for not getting it done in the time already allotted.
Oh, and never cancel a case.
