A bar owner in Spain has stopped accepting card payments due to the high transaction fees charged by banks for small purchases. The owner, Mar, believes it is illogical to pay a bank commission on inexpensive items like a 1.30-euro coffee. She prefers customers pay with cash, even encouraging them to write IOUs if they lack it. The decision highlights a growing frustration among small business owners regarding the cost of digital payment processing. This practice is not uncommon in Spain, where cash remains a popular payment method. The bar owner’s stance has sparked debate about fair banking practices and the financial burden on small enterprises. It reflects a desire to maintain profitability and avoid unnecessary expenses.
