I wonder if the local state government has the time to investigate this if you report it.
A sting operation to levy a big fine, followed with reporting by the local media will scare the cheating vendors.
Do we think that is widespread or simply a product line glitch. True, they should be checking weights, but if, like most products (even including drugs) only a small fraction of products are weighed. I certainly don't doubt some packages are off weight, but it seems unlikely this is intentional or typical. Having said that, I'm pretty trusting of such things - not necessarily in overall ethical behavior of companies (think: Shrinkflation, for instance.)
IOW - if you can shrink it, why would you miss label it?
