I do think the stores factor in the loss of items. I have seen this same older man almost weekly at the grocery (has been going on for at least a few years) He takes handfuls of nuts and eats them, handfuls of grapes, even an apple or banana he does this every week and the store knows it. I have even said something a couple of times and so have several other people the manager says that the few cents in items that this man eats each week isn't worth his time trying to file charges on him.
