My last flight to Zurich(in coach) was delayed 3 hours in leaving Dallas so they made an annoucement that on their first beverage pass through there would be no charge for drinks but they would charge for the rest of the flight. The person next to me asked for some wine and a coke(many people did this). He saved the wine for dinner. When the FA noted the wine bottle on his dinner tray, she demanded $4 from him. It took over 5 minutes before they left him alone.
