Ah, you know it was indeed my intention to point out to player the fact that if you throw the cookies/biscuits at the wall, it makes noises and that can distract a guard and make them investigate it. I didn't say anything about directly throwing them at the guards, because I intended for that mechanic to be "discovered" rather than told. But it seems most players ended up just chucking the biscuits at the guards to stun them anyway haha.
