How to treat fellow villagers who can't speak dialects?

It is normal for fellow villagers who can't speak dialects. Maybe they just came from other places, so they are not used to the local dialect. Many locals have lived in other places for a long time and come back when they grow up, so it is normal not to tell lies. Doesn't it affect your communication that they can't speak dialects? Impossible, so don't affect your communication just because others can't speak dialects.
