The motherdairy booth operator in 903, Arjun Marg DLF Gurgaon is cheating the public. The unit prices of items are deliberately not fed in the machines. These are typed in each time. This gives plenty of scope to the operator to overcharge. When it is detected, he immediately tears up the bill mumbling sorry sorry. Most of the time we do not have the correct unit price to compare. He particularly targets old ladies, servants, illiterate people. Also people buying many items are his targets because he can easily overcharge in 3 or four items. The concerned authorities have been told but no action is taken.
