“Tipping is a thing of the past” is just a completely false statement, given it’s the norm in the most economically powerful country in the world and not at all u heard of elsewhere (food delivery in many countries, high end restaurants in the UK and elsewhere, etc.) If we’re being generous we can call the claim is vs. ought distinction, except the phrasing doesn’t even leave room for the ought interpretation. It’s just a falsehood (were it was true).
