Two families arrived at airport rental desks with valid bookings and valid credit cards. Both were refused their cars. In neither case was the refusal justified by the companies' own published terms. The resulting costs — alternative transport, forced insurance purchases, stress — landed entirely on the customers, while the rental firms faced no consequences until a newspaper columnist intervened. The first case is the more egregious. Enterprise's branch at Carcassonne airport refused a First Direct Visa card on the grounds that it "did not accept cards from online banks." First Direct is a division of HSBC, one of the world's largest banking groups, and Enterprise's own terms accept Visa. The branch doubled down in writing when challenged. Enterprise only admitted the error and refunded €440 in expenses after the Guardian contacted them — three months after the original complaint. No compensation for the disruption was offered. The second case involves Flex To Go, operating through Holiday Autos, at Warsaw airport. The customer's credit card bore her initials rather than her full forename. Holiday Autos' booking confirmation warned against "abbreviations" but did not specify that initials counted. The customer was forced to pay £145 for redundant comprehensive insurance to release the car. Neither Flex To Go nor Holiday Autos addressed the ambiguity when challenged. Buried in Flex To Go's terms — which customers only received at the collection desk after completing the transaction — are clauses requiring customers to pay for "minor expenses for ordinary use of the vehicle" including refilling screen washer fluid, and to carry out daily inspections of brake fluid, oil, and coolant. These onerous terms were neither highlighted as required for unusual contract clauses, nor flagged by Holiday Autos as the booking intermediary. The extraction mechanism is elegant in its simplicity. Rental firms publish broad acceptance criteria ("Visa, Mastercard, Amex") while individual branches apply unpublished restrictions at the point of maximum customer vulnerability — an airport desk, luggage in hand, family waiting. The customer's only options are to comply with whatever additional charges are demanded or abandon the booking entirely. Refunds for the original rental come through, but the collateral costs rarely do without media pressure. The intermediary layer compounds the problem. Holiday Autos sells the booking but points to Flex To Go's terms; Flex To Go's terms arrive too late to act on; neither entity takes ownership of the gap. This is a classic principal-agent information asymmetry: the customer is the only party without full information at the moment the decision must be made. The practical advice is sound but reveals the structural problem: customers are told to read reviews, carry the right card type, ensure names match exactly, avoid Apple Pay, and study supplier T&Cs before travel. The burden of navigating an opaque system falls entirely on the consumer. The firms face no regulatory penalty for applying terms that contradict their own published policies, and complaints only produce results when amplified by press coverage.
