I’m certain I’m not the only one who does this.  In fact, I actually usually take the second package in regardless of what it is.  Clothes, cans of soup, boxes of cereal, deodorant… it doesn’t matter.  The front item has a greater chance of having been manhandled, dropped, sniffed, crushed, or simply pushed forward for newer, fresher stock to be placed behind it.

It only makes sense!
