After using a debit card for several years and enduring the hassles with multiple swipes, or leaving the card with the attendant, we have used cash only for the past couple of years. I am less apprehensive about carrying the cash than I am about credit card security. We use a bank that refunds all cash machine charges, so we don't have to carry a large sum for the entire trip. Still have to make two trips inside, but I need the break. Cash discount is ok also.
