Monoprix. We have history. Years ago, on another flight to Paris, KLM had lost bags and did not retrieve them until the end of the trip. We received permission via Air France to purchase up to a certain amount and get refund. We went on a shopping spree at Monoprix, purchasing turtlenecks, clothing, snacks. Supermarket Sweep style. Unfortunately,  we found out we were not allowed to be reimbursed because it was a KLM flight. Unbelievable. We still have fun memories of Monoprix though. It is a delightful place for beverages, snacks, fromage and their patisserie.
