In Spain, businesses are legally allowed to accept only cash payments, but they must inform customers clearly about their policy. This practice has become increasingly common, sparking debates about fairness and legality. While many businesses cite exorbitant bank fees associated with card payments as their reason, others seem to prioritize cash payments for tax evasion. It’s important to note that while refusing card payments is legal, businesses are required to accept the legal tender of the country, which is cash. Therefore, refusing cash payments is illegal. The widespread use of card payments in Spain has made the absence of this option seem unusual, but the legal framework allows businesses to operate on a cash-only basis as long as they clearly communicate their policy to customers. Ultimately, the ethical implications of cash-only businesses remain a matter of individual judgment, but understanding the legal framework provides a clear perspective on the practice.
