That does not mean you should. If you’re going to order small, you should tip big and I don’t think that is remotely controversial?
I don't see why that wouldn't be controversial. You're thinking of just wealthy people and not middle class. I would be losing money every month paying premium for small orders. I know this because i've done this for months (was very sick for awhile).
And since I still believe in tipping people because I understand that they're not being paid even minimum wage, I opted to just not order at all now.
