make sure to speak to the manager or other person in charge when you find empty shelves

that will usually get some attention on it, the bread and dairy isles get beat up the most because they are usually only worked once a day unless someone complains (from my experience). The bread isle was my space when I moved on and it was almost impossible to keep filled because a bunch was vendor controlled but I always had store brand or generic stuff to fill the empty spaces before I’d leave for the day

someone was supposed to face it a few times a day but rarely did that happen unless the manager noticed or someone complained

polite customer complaints are powerful motivation in my experience
