Do you have a Weighing Machine in Your Kitchen.
Quantity is taken for granted.
We buy our domestic needs like clothes and grocery items month after month.Too much care is taken to see date of manufacture,expiry date or shelf life but no serious look is made on quantity of the product in the pack in case of many items.
Lets take Rice which we south Indians buy bucket loads each moth.We see the color,shape,smell,origin and broken bits if too many and grade it our self and if price is satis factory we tell him to give us 1,2,3,4,5.10,25 or 50 kg packets.
The Store Keeper has already made packets in this order and he just puts it in the cart.There ends the purchase of Rice.You now go to other items and start your own self made quality assessment of each product and buy it.Everything is packed and you just cart it.Have you ever weighed the packets each time you purchased for correct weight printed on the label.
A Chinee in USA was receiving his 1 lb Bread from his Bakery and was weighing it at his home and after several days he found the CV % of Bread was significant and complained to the Bakery that he was receiving his bread with weights out of limits as per his calculations.The Baker asked for seeing his calculations and told him that in future he would get his Bread as per his calculations.From that day onwords the Chinee got his bread correct to 1 ib and had no complaints.What happened.? I will tell you later.
