What would the lady in aries’s story say if she was given a plate of soup in that hotel and told that the previous meal a non religious guest had put something into that particular plate of very doubtful kashrus origin? Would she care that the guest when challenged had said ‘it’s not my problem’?
Ps Where do gebruchts get their name from? I assume that because gebruchts means broken in yiddish that it comes from breaking matzo into soup or even coffee. (Yum!).
