If “full of flour” means unlimited witness data, then I think the restaurant actually fucked up at some point and nobody has the balls to fix it.
Some flour (like maybe 400kb of flour) seems like a reasonable design choice that allows everything you can think of that needs to be made with flour.
The idiot(s) that said unlimited flour wouldn’t cause the restaurant to be filled with flour because nobody would ever in their right mind do that… did not have enough of an adversarial mindset.
