Groceries made easy: Reaching the items in the back is never easier
Reaching the top shelf for a short person is not even half of the struggle compared to the battle anyone has to face while grabbing the items stacked way back on the shelves. Now either you could ask someone for assistance which is exactly why the staff is there, or if you are an introvert and lack the social skills for this, you can try it yourself.
The latter can be done either, but you can make a scene out of yourself as you make the entire shelf fall, or things can end differently and cleanly if you use this trick. Most of the shelf dividers can be pulled outwards and dragged along those items in the front for you. As useful as this hack is, it is surprising that not many people know it and end up creating a mess in such situations!
