And they're supposed to do precisely what with the body?
I suspect that as a practice they put the body wherever it's going to be farthest from the next passenger. On a full flight, that's likely be up front.
Perhaps BA was abrupt with the passenger, but we're only hearing one side of the story.
Far from complaining, I'd go home, hug my wife, and consider how good I have it.
I'm honestly surprised at some of the reactions posted here.
