Locks????? LOL.. its a wide open area that is seldom used.. I hardly ever see any bags in those things including mine.. I usually keep mine in close site although I do admit when I'm in one of those cubby holes online; I will leave it unattended to get a drink or use the rest room which isn't the brightest thing to do, but short of packing it all up again, is there a choice.. and NO not getting a drink or not using the rest room is not a choice in my book LOL

As for the head sets; I think you are wasting your time worrying about it.. this is a definite case of MYOB.. I mean who cares.. the FA will give them some if they want them.. these things are a dime a dozen. I too have these in every drawer at work, in the house and in every cubby hole in every travel bag I own.
