I've spent a bunch of years in sales, and none of this looks even a little bit unusual, except the part about expecting the technicians to comb their hair. Like @EricE said, there's a wrong time. There will always be a few - or maybe a lot - who don't get it, and will push for a sale when it's the absolutely wrong thing to do. But I hope it's rare.
Full disclosure: I used to be a Comcast subscriber. Yes, they're really that bad.
