I had them come round in the lounge at ABZ two weeks ago and stick one on my suit hanger, at the gate they were checking pieces up and down the queue and said there should be one on my shoulder bag. I pointed out that they had already tagged the other bag in the lounge, but they were adamant that the shoulder bag should have been the correct one tagged, so it got one too - not in exchange but in addition! I now had two pieces and both were tagged. No point explaining about seat numbers, they are "only obeying orders"

Whilst I could have ripped either or both off, I didnt bother and just put both into the overhead locker as that's what you are supposed to do when you are sat in 1C on the A320
