They are telling you what to do because there is only 1 person on the team pushing dairy. You are not going to sit in the dairy cooler waiting for stuff to back stock when there isn't anything
Get out to the salesfloor and push.
Oh and take that snow suit off it's not that cold in the dairy cooler
Pas are just giving guidance to get the whole FDC truck pushed in a timely manner. As a pa I push all bananas produce and fresh meat plus the specialty milk and have to do vendor milk.
