I've been waiting for the story to come up, in vain.

So, here it is. A couple of young ladies at the school that my son used to go to did a science thing to prove that inexpensive vitamin C drinks are inferior to expensive ones. They found that this product, much lauded by its makers as containing copious quantities of the stuff, was in fact very deficient.
Having contacted the makers, they were given the brush-off, so they publicised their findings.

Here, the Managing Director, or someone claiming to be him, is on TV in full damage-control mode, striding through fields of Blackcurrents and apologising for 'misleading the public' and blaming quality-control and manufacturing systems for the problem.

They are liable for a huge fine for false advertising, and it ought to be much larger. For many years they have made the same claims, and mothers have been giving their children lolly-water, thinking that it would reinforce the kid's immune system.

As for the fine, it is about five times as much as I would be liable for for doing electrical wiring without being an electrician.
