A friend and I
Languages evolve. If people say “me and X” over the formal “X and I,” then the more correct answer is “me and X.” The only people I’ve seen quibble over this matter is English language teachers in school.
My point is, even though getting it "wrong" is very common, this grammatical rule is still far from dead in practice, and so simply offering the correction doesn't necessarily mean the person is being purely pedantic.
Of course this is all to do with "me" vs "I". I agree the strict order of the nouns is indeed almost dead in practice.
