False weight scam captured on camera

In this video, a grocer has attached a bag to the scales. At about 28s in, she slips the bag off the table, adding weight. At about 34s, she lifts them back up. It's the oldest scam in the (good) book.

A false balance is abomination to the LORD: but a just weight is his delight. — Proverbs 11:1

To solve the problems embodied by this recording, I propose a new international compact on Weights, Measures and Vertical Video. [via]
