You’re in Athens, ready to grab a quick souvlaki, and oops… the street vendor smiles but shakes his head at your card. Some places still vibe strictly cash-only, and nothing kills the mood like fumbling for plastic where paper rules.
Walking tours take you into local nooks — hidden cafés, tiny shops, food stalls that don’t even know what a card reader is. Keep a little local currency in your pocket so you can eat, sip, and shop without the awkward shrug. Cash = freedom to say yes to the moment.
