"Fill That Shelf Overhead"

In the 80's I remember over the Christmas holiday when I worked for a retail store and we put overhead shelves up over top of shelves in every spot in the store that we could and stacked the overhead shelves full of holiday items as all the items always seem to be sold over the Christmas holiday. Of course back then online shopping was not that big and hot as today as things have really faded and changed over the years now. Maybe it just means I'm showing my age and remember back when.
