Not defending them, but the pad weighs very little to begin with. As the meat juices seep into it, it increases in weight.
And you are not going to squeeze the juices out of a pad. Perhaps you might pour them into a pot from a simple tray.
If they give the meat a quick rinse and put it on the pad, you are paying for rinse water.
He puts the pad AND the chicken on the scale and it’s still underweight.
Correct. The pad itself is part of the "tare" of the package, and doesn't count towards the net weight of the packaged item. As the meat sits on it, some liquid will seep into the pad, but that liquid is considered part of the weight of the meat, so it's arguably legit to charge for that.
I don't know of any place that allows charging for the "gross" weight of the package -- the meat plus all the packaging. That's not legal anywhere AFAIK.
I have seen this guy’s videos who was on top of this underweight situation at walmart. He does account for the packaging and pointed out that the shrimp is almost a quarter water. So once the shrimp thaws out and drains, you’re left with considerably less. There was a brand of ham that was prepackaged, sliced and it was underweight many times by almost half!! Sugar, kitty litter- so many products that we have been buying for decades, Lord only knows how much we have been ripped off over the decades. I did see that he was asked to leave a Walmart when he went in to do more weighing of their fresh meat boneless chicken breast.
Ever notice, especially on ham they list "Water added" as a content?
