Reply To: Awkward kashrus situation – advice?

I think she also said “I don’t eat at other peoples houses.” If the topic comes up again, she can explain this is her family minhag. Similar to not “mishing” on Pesach. The person who they don’t eat by might be their best friend/neighbor, but this is a minhag they have. Therefore no offense should be taken. Even wouldn’t eat at the Rabbi’s house, irrelevant of their halachic/haskafic differences.
