There are crew who are particularly picky about where their bag is, and there are passengers who are particularly picky. In that case, the crew wins because they are there first and they are in charge.
Rule of thumb, don't move someone's property. Sure, rotate a bag if someone didn't put it in in an efficient manner, but don't pull it out of a bin to move to another.
That is true. I am just surprised the airlines dont designate bin space for crew. It seems like the crew on this flight overreacted and it could have been solved without ejecting a passenger. The blogger should release his video to show what happened.
