That second video is stupid, he didn't do anything rough with the packages other than sliding them in, or tossing a 0.5lb box onto a shelf, or dropping them 6 inches. This is all pretty common when the boxes are automatically handled, and they don't get treated much better when they're stacked.
Yeah, it looks bad, but the dorks giving the commentary make it seem a lot worse than it is.
And the driver was stupid to do that right on a public street in front of the customer.
