Piri I was joking a bit, I am really positive about zero packaging.
People are messy though some because they do not care and some just because they are not so coordinated.
I was imagining a huge supermarket like Maxima XXX with every product being loose and put into containers by the people shopping and a bit of flour spilt here and a bit of sugar there and some rice and on and on. Someone would have to be cleaning all of the time. 😆
