I think the thing that irritates me the most is the championing of this man by the press and the way that he thinks he's won.
BA were always going to get the bag back to him. It had a tag, he filled out the loss report properly, there was no reason it would vanish forever. He was always going to have to wait at least 24-48 hours for it to be returned and it was always going to be delivered personally to any address he chose. Perhaps he has to think he's won some little victory to justify to himself spending the "undisclosed sum" which I bet he regrets now. I bet he secretly hope the saga would run for longer so he could get his moneys worth, but in reality the bag was probably being loaded on to a delivery truck long before he even wrote the tweet in question.
