My question is...how long was it doing that before they caught it? You see no other boxes around, and no other employees. Could be been tumbling for hours.
However, my beef wouldn't be with the shipping company...it's with Amazon's inability to keep merchandise from shifting in the box. Has they used appropriate voide-fill, it would have tumbled once, and stopped. When Newegg sent me a hard drive, they only used those inflated plstic bags, but all had popped by the time it got to me, so the hard drive bounced around freely in the box.
