> no, I tip in establishments where the workers are service workers who explicitly asking for tips, as well as for specific transactions where tipping is customary hence expected.

Hopefully you see the inconsistency here? You mentioned that minimum wage has not increased in a long time so people making are underpaid (true). And that tipping is somehow the solution. But unless you tip everyone you ever interact with that might be making minimum wage, that's a highly inconsistent position.

Instead we can simply raise minimum wage to a living wage and outlaw tipping. Fair to everyone.
