OMG! Someone's got a hold of IroNat and turned him against WalMart! Let's hope he doesn't get WDS - Walmart Derangement Syndrome! Stay off social media; its corrupting you.
I'm going to Walmart later today. Word on the street is that they're having a sale on their Casio watches. 
Wow, a Casio watch is nothing sneeze at!
I bet this goes on at more stores than Walmart, especially if they use pre-packaged meat that comes direct from suppliers, which many of the big chains now do.
From now on I will check the weights of packaged meat wherever I buy it.
I was in ALDI once and the state inspector was in there checking weights.
They do this occasionally at grocery stores.
