The judge would use this sign to make an example of you.

As they should. It seems like common sense that this sign should be enough and anybody that ignores it "is an idiot that has themselves to blame for the discomfort of food poisoning". But it's suddenly a whole different story when your grandma of 82 has died a painful death from severe salmonella infections just because she forgot her reading glasses that day.

The risk of death is tiny but nevertheless an unacceptable risk to assume just so some other people can keep buying their snack for a couple of days instead of shutting down the machine.
