I used to have a summer job in agriculture, peeling flower bulbs and also planting tiny little plant shoots, but there are a few things I don't understand.. 1) how do they remove the pit out of olives or cherries and keep the fruit intact, whenever I try to do that they are left mangled in many pieces.. I don't see how they get them out. 2) how do they process mangoes so that the stone is removed, but the fruit is in neat pieces. Whenever I try to eat a mango it becomes really messy, it is impossible to eat that fruit. 3) how do they remove corn from the cob, those things are impossible to get off!
