As a side line I found a way out of the Zambia flour shortage. I went to the flour mill and discovered that there was no shortage of flour , they just did not have any bags to pack it in. I bought a 75 Kilo hessian sack of flour and set up a sale stall in the bar of my local social club. I sold it all at a large profit and got loads of free drinks. I just told people to bring their own containers so that I could weigh the flour into them.
Later I did the same for cooking oil, again I found there was no shortage of oil only of bottles to pack it in. I bought a 50 gallon barrel of oil and sold it from the bar,people just bought their own empty bottles for me to fill. More profit and more free drinks.
