MOST places we've gone to do laundry will take credit/debit cards for CASH but usually NOT for services. I mean you get the case and THEN put the money into the slots not using the card to pay them directly. SOME places have attendants to do the transaction and some use a debit/credit change machine where you put in the amount you want then swipe your card. You should KNOW how your particular card treats that kind of transaction. SOME of the rip off cards will call it a "Cash Advance" so if yours does this be sure you don't carry a balance on it.
