One day at the food bank where I work, 20 boxes of cabbage came in. A new staff member was advised by Arty, a longtime volunteer, to lift them from the bottom.
Within seconds, however, the staff members tried to pick up a box from the sides. The bottom fell out, spilling cabbages all across the room.
"Next time, lift from the bottom," Arty admonished, "or heads will roll."
