You know that red “Hot Light” in the store? When it’s on, fresh donuts are coming out. But here’s the truth: they’re always making donuts if the light is on.
The light isn’t tied to the fryer. It’s just a marketing trick. But the oil doesn’t care. It just keeps bubbling away, waiting for the next batch of dough.
If you see the light off, run. Either they’re cleaning the oil, or the apocalypse is coming. You decide which is worse.
