I have seen a bear flatten a tent to get at (and then try to eat) a foam pad that it thought smelled like food. The tent occupants (outside the tent at the time) had more or less the same idea you did.

Not saying it couldn't happen if I was careless, but I double bag my food and that goes into 2 Rubbermaid type clear boxes with the latching lids.
I also made homemade silicon sealer gaskets for the lids. I don't prep food on them so I'm not too worried ;), but then you do never know.
I try and stay at the less used campsites because you never know who did what at the 4-5 star sites and whether or not the local bears see it as a possible food source.
