I worked in a place, for a very huge multinational company, where we would import 'rags', they would come to us bales and they would be opened, without washing, then pressed and used again for new designs in clothing, or sometimes just sent straight to the stores, of course stopping at a distribution center first, to have a hefty price tag added.
My attitude on the bins was "Bring it". If you could only have SEEN the things I've seen in the bales. Perhaps one of my most "Safe for work" stories was us requesting 1000 pounds of lace household curtains which seemed to multiply on cutting open the bales. On opening the bales, I found a very cool shower mat. Totally unexpected.
