Once with a group of friends we arrived at LAX very late (the minibus never turned up) for an AA TATL flight in Y and very hungry. As a result we all visited a takeaway by the gate, then boarded with hand luggage and pizza. The lady sitting next to me in the window seat said she didn't mind. Although when the meal service was quite slow to start some of my friends who were still eating became less popular as time went on.
