Gotta say that's some kind of messed up analogy you got yourself there.
Disclaimer - I in no way blame Trump for Covid nor the deaths in the U.S., if that's the point.
However, in your analogy, the manager should have a) destroyed the cheese if he know that it was bad and/or b) told you why you shouldn't use it at the very least. So yes, I do blame the manager in that scenario.
