Inaccurate pricing, Bad attitude

I went to the store this evening to purchase some streaky bacon. I get to the bacon rack, and there are 2 labels on the railing above the rack with streaky bacon. The one is for Escort Round Bacon, the other for Escort Viennas. I didn't even notice the railing beneath the rack because there were no prices on it. And on the aforementioned lavel there was no arrow pointing to the product. Hence I assumed the price app**** to all Escort bacon, and the price was R21.90. I get to the till and suddenly it scans as R29.99. I raised an objection at the price difference. The friendly cashier calls his controller, Nandipha, and I explain the situation to her. We go to the rack together and she acknowledges that there is only the one price for Escort bacon there and calls someone to rectify the problem. \Well what
