Alert! Intrusion! 4
I was just wondering… The people from the supermarket in your neighbourhood might know everything about a person from the things he/she buys from the store. You come to the cashier and she tells you “Oh, you don’t need that bottle of mineral water because your wife just dropped by and bought too. And are you sure you want to buy those cigarettes, because you have enough at home, you know?” One can try to bribe a vendor one day just to find out some “secrets” about the neighbour next door.
