Don't know how you would fake that, it's pretty much what I pictured. Just because the packages are being handled roughly doesn't mean the contents will necessarily be ruined, if the cost of the item is low enough then shipping issues are just part of doing business. Stuff I've gotten from china took long enough that they could have shipped it three times for all I know.
FWIW you could probably take similar videos in lots of other sorting facilities, I stopped using UPS a while back when I discovered my packages (expensive racing engine parts) were routinely being thrown over my gate into the side yard.
Any time you have a situation where people have more work than they can physically do you will have some exhibit this kind of behavior, they're probably just trying to make a quota and keep their jobs. There's currently quite a few reports of workers being forced to work long hours in hazardous conditions here in the US with Amazon fulfillment centers and delivery operators. I know FedEx dropped it's contract with Amazon last year, hard business decision to make but I'm sure they had their reasons....
