It’s kind of a low-grade risk though, don’t you think? I imagine it’s unlikely we’d see major changes over “some stores lost a few hundred grand due to a cyber attack”.
I suppose it could expand, but even still, there’s plenty of non-perishable foods. It would be annoying at worst, but maybe never outright dangerous?
It is not a low grade risk at all, these represent extreme health risks to the customer.
It may be some time before staff notices a unit is heating up. And if customers aren't paying attention and grab something biologically fragile like milk they could get food poisoning that could hospitalize you for days.
