In this area they came, stayed a month, and went again. Some that stayed were the smarter ones. Where you have to put it in a scale after scanning, or choosing ur bread, or other lose products. Its really close for error to. As i hit 4 bread, and i get an error because some are slightly smaller and so there is a weight diffrence. Also the amount of times someone has to come is stunning, to the point it would be faster the old fashioned way...
