Legit that's what my last employer did when a soda machine had a recall on one of the diet sodas.

Just pulled however many quarters from a register, bought all of them, and boxed them up with LOTO tape all over the box. When the guy came in to resupply, he was given the box and pulled the quarters out of the machine and gave them back.

He also left a small stack of reimbursement tags to be left on the machine, fill out what the soda was, what was wrong with it (expired, wrong soda dispensed, etc), and whoever came back would leave the cost taped to the tag with the office to return to the right employee.

I think it's quite the opposite, a judge would mock you for such a lousy attempt. It's pathetic, disconnecting the machine is a simple process and it ensures all patrons are safe, not just the ones who notice this tiny sign.

A decent example would be a elderly customer who is visually impaired. They may already frequent this machine and know what buttons they gotta press for their favourite snack. Sure sometimes they get it wrong and something else pops out but that's ok they aren't too picky.

But now introduce the danger of one of these options being an actual poison and the seller admitted they are aware they are selling poison among food? The judge would use this sign to make an example of you.

Could just unplug it.
