The fees just straight up don't exist for customers now. They havent for decades.
Its even illegal to charge one at all if your bank has a few billion in assets.
So at worse a company might pass their processing fees onto their customers.
But banks can't charge you one and most companies don't either. It's just a cost of doing business.
So only the poorest shittiest banks, and the shittiest companies charge one. That or small businesses that can't afford to eat the 2.5 to 3% that's common.
But functionally debt cards are just a free service as far as the consumer is concerned.
