NONE of these people are right!! I am being as SERIOUS as I have EVER BEEN right now!! I applied for a job at a place in North Tonawanda (I don't remember the name of the place) where they repurposed jean material (like Levis) and as we passed through these sets of flaps there was a fine powder on the floor. OK, seriously now, the white powdery stuff is some sort of wicked finely ground paper and cellulose mixture that is applied different food stuffs (like shredded cheese) that prevents it from sticking together and forming clumps!!! HAND TO GOD!!
