Just before using the grains, they would be required further cleaning to remove any bugs, soil knots and any other impurities through a manual process. Rice would be cleaned daily but wheat would be cleaned monthly before being ground to flour. This used to a bit tedious task. In a flat large pan, we would pour wheat grains on one side, and push the cleaned wheat grains to the other side forming another heap. The bugs and insects in the wheat would scuttle to the clean heap or vanish back into the heap they came from as soon as they were exposed. Those small insects needed to be crushed with the back of nail outside the dish. This de-bugging process would take hours.
Irrespective of where we spend our holidays, at our own house or at some relative's we were expected to help in the process. It used to be fun, so we never complained. One afternoon my aunt set me to this task and promised me to pay 1 paisa (hundredth portion of a rupee) for every bug I found. I complained that this is too less a compensation and I want 1 rupee per bug found, hardly knowing what a rupee per bug would actually mean. The negotiation, my first ever probably, settled at 2 paisa per bug. By the end of the first hour I had earned a whole rupee.
Switch to present, I still work in a profession which requires periodic debugging; I am software developer. But then I earn much more than a rupee per hour. My first ever negotiation and a paid job didn't go waste after all. Mind you, the payment I was demanding was way lesser than the market rate, even then :).
