Is it bad etiquette to use a credit or debit card to pay for single figure amounts at the POS
Etiquette doesn't really come into the picture here. The business offers a service and I choose to accept it. Personally, I use my debit card as much as possible. For every transaction, I record it in my checkbook. Then, when I do reconciling, I know exactly how much I paid for various categories of stuff. Good for budgeting. Most often my purchases are over $10 but when they aren't, I have no qualms about using the card.
