In hot summer may in Chennai a open truck daily carried potato from harvested place reached and the consignee at Koyambedu market found the total tonnage received was 5 percent less than invoiced weight. . What could be reason for 5% less? Pilferage ruled out.
The driver stopped in a small restaurant to full his stomach. He sold the 5% potatoes to him and he promised him to serve free masala dosas for one year! My out of wild box thinking.
Besides your super out-of-box reasoning, just brood over the key words in the question. They are “hot Summer” “pilferage ruled out” “ open truck” “harvested place” These three hint at the answer. The loss occurred during the journey. Natural cause. What it could be?
