He is sharing some of the savings from tax evasion with the customer.

I do not know if he can accept electronic payments from a debit card on the phone. I presume Zelle/Venmo is simpler than figuring out a system to separate debit cards and credit cards.

>just that it's exceedingly rare

Discounts for non credit card payment methods (such as ACH/debit card/Zelle/Venmo/paper cash) seem more and more common to me. Bigger businesses likely won't engage in tax evasion allowing for bigger discounts for paper cash, but fewer and fewer of my expenses are worth paying with a credit card.
