The intrepid CSR is busy finishing the order. After reading back the order to verify its validity, the following exchange takes place.
CSR: Will this be cash or charge?
IC: Actually I'd like to use my debit card. Will that be okay?
CSR sighs and presses the "charge" button
CSR: That would be perfectly alright. Can I get your card number?
IC reads card number.
CSR: And is that Visa or Mastercard?
IC: It's a debit card.
CSR inserts gun into his mouth. Makes note that IC will be next.
