I have to jump in here! Devorah, if it bothers you so much, next time you see someone who looks like they care about kashrut, go up to the and say “I don’t know if you realize this, but the grilled cheese and baked goods here arent kosher.”
Leave it at that. You’ve “done your job” and you dont have to embarras them. e
I would personally leave it alone because I believe everyone has to make their own decisions. I dont like when other people tell me what to do (unasked, I give my Rabbi and certain other people permission to guide me according to halacha) but I would be very pissed off if someone tried telling me what was ok and what wasnt. Then again, if I didnt realize it wasnt kosher, I would be very happy if someone told me. So just go easy on them if you decide to speak to them.
