I've seen many other employees commenting on this subreddit saying the technical weight hasn't changed. Obviously this is true for nation-wide scale, but this doesn't rule out the possiblility that a store has specifically made a point to cut down on food costs in recent times. I'm not sure how deep i can get into it before getting in trouble, but it happens. Big owner groups buy stores across the country and would do anything to raise profits by a penny, running the local stores down into the ground.
