Not that unusual for Credit Cards, but not sure that it's legal to charge for a true Debit Card.
From: https://www.valuepenguin.com/credit-card-surcharges-convenience-fees
"Surcharges cannot be imposed on debit or prepaid debit transactions. This holds true even if a cardholder chooses "credit" as an option when using their debit card."
That is what I thought, but couldn't point to something that said it.
