machines do most of the sorting of packages - they dont care what side up the box is as they have scanners on all sides. They also dont care what gets dumped on the box a container is upended by a robotic arm onto the conveyer belt.I've only had eggs shipped once, so far. The eggs were wrapped very well and shipped very well. Hatch rate was great!
One thing I noticed is that, on the outside of the box, he had written not just "Fragile" but "Fragile, live embryos."
Maybe making it sound more serious/scientific/whatever really got the attention of the workers. Like "Hey, this is something important, I'd better be careful."
Most people don't intend to do a bad job. Just like the rest of us they get into a routine & do whatever gets things done the quickest. Knowledge is power.
the poor old postie only gets the last mile and we beat him up
