“Gaon, Can you agree with me that my plate is “keli shel lo’kayach b’rishus mocher” that is koneh for the lo’kayach,”
As stated above, ‘kugel’ is a diff category, as its meant for the taker to keep (for the lomdim: it might depend if you can be mekadesh one with it) and thus you can be Zocheh with any kinyan. Now given the shul has a status of חצר של שניהם (see CM 340: ?) you would be correct!
“turn my back for a second, and the prized kugel is missing! Maybe someone was moreh heter that I was not koneh it!”
Forget about that you made הגבהה…but the ultimate chuzpah to take from the Rebitzins plate!!
I guess its a דור של חוצפה יסגא!!
