That would be so stupid. First, applying a constant force to a liquid isn't going to make it slosh. Remember as a kid at the beach, putting water in a bucket and spinning it? The water doesn't go anywhere and it doesn't slosh (unless you apply something besides a constant centripetal force, which a centrifuge wouldn't). Second, I'm sure anyone who has packed a box has shaken it and listened, the noise is just not that loud. I packed one a few days ago and couldn't hear it over the sound of a box fan. Centrifuges are ******* loud, especially if they're spinning heavy-ass boxes. Hell, ANYTHING that's mechanically moving **** around like that is loud. You'd never be able to hear the sound of sloshing over any mechanical system. And why buy a fancy new system when you could just
shake the box?
Also, why would Fedex care? They need to make a nominal effort so the feds can't charge them, but why go out of their way to reduce their business? I get it when there's some moron clerk at a Fedex store who has decided that it's their precious little fiefdom and checks every box themselves because it makes them feel important, but at a Fedex distribution center? Why would they do anything that slows down distribution and potentially loses them business? Nothing about that makes sense.
It's almost certainly a coincidence. Someone who works for a delivery service (
AleWatcher? anyone else?) would know better, but I don't believe that the same trucks handle incoming and outgoing packages at the same time. That seems like a logistical mess. Possibly someone at the center is checking boxes more thoroughly, but, again, why? What's in it for them? It's more likely some **** drove a forklift through it.
Also, FWIW, a package coming to me went through Orlando successfully on Monday/Tuesday.
