Posted this before, but it is so relevant here.....
The last flight I took to BOS in WT, I was slightly dissapointed to discover that my meal pref (a lacto vege) hadn't been registered & therefore loaded, and I thought I might go hungry. The FA however had other ideas and gave me a tray minus main course, and asked could I wait a few minutes. After service finished she asked me if risotto was ok, & then produced a mushroom risotto on a First china dish.
At that point I would have almost paid £4,000 (to move seats) for the misery guts next to me to shut up about it, as he complained that he was a Gold and hadn't received the food upgrade or any upgrade, he then complained about his seat, the IFE, and anything else he could find. The poor FA was really appologetic but what was she supposed to do about him only paying for a WT seat, and finishing the meat meal he'd asked and payed for. He was a nightmare the whole flight. Earplugs and NC headphones are a godsend in these situations.
I did ask whilst he was in the gents if there was any other seat available, but alas the flight was full. He was a nightmare and I'll get off the flight if I'm next to him again, refundable ticket or not.
I've seen a little old lady on a train using a pair of scissors to deal with a bloke who had gone to sleep with loud music blaring out of his headphones (so loud he almost needn't have bothered with them). He didn't wake up as she cut the headphone cable, & she got off two stops later, as did I, so I never found out what happened, but I bet he was annoyed. Shame scissors are banned on flights now.
