Bravo...man, I wish more people would do that! I can't count how many times I've seen folks place their bags and then "presume" the bin will close, and then when it doesn't it becomes a mad scramble for the FA to shuffle things around in nearby bins before aircraft-doors-closed. It's a big reason why I no longer allow myself to doze off before doors-closed...I don't want to awaken later and find my bag is not where I originally stowed it.
