We bought 2 bundles of spinach (1 red & 1 round) from Sheng Siong supermarket this morning but was charged for 3 bundles (2 red & 1 round). We didn't realised it until we got home when we, out of curiosity, checked the receipt. Could this overcharging a mistake on the part of the cashier? Could this "mistake" be made frequently without the customers knowing it? We seldom check the receipt against what we bought as we trust the supermarket. We could have disputed the matter but the supermaket is a distance away and it's not worth our time and effort to travel all the way to rectify the issue. I blog the matter so as to bring awareness to all.
