i don't agree with the wording or treating it as universal tbh. i always went by whoever invites the other out pays for the outing. my culture is leans towards a bit more traditional, the man is expected to pay during the get to know you stage but once they're in a real relationship then the woman is expected to occasionally pay to display financial independence. my bf grew up with a diff culture but similar mindset so this works well for us but i don't think it's one size fits all by any means
