Bad attitude from cashier and pricing and barcodes

Good day to whom this may concern<br> <br> I walked into the Kwikspar in grahamstown, at 3:40AM, and i picked hamburger patties and bread, and when i got to the till, the cashier said this item will not scan because it hasn't been put on the system. i politely asked why is it on the shelves then? and why isn't it on the system, and she rudely responded by saying its the managers job, and i thought she was just exhausted perhaps, and i asked her who is her manager and she rolled her eyes and gave me the name, and i said because you're rude im going to report you. im really in disbelief that i was treated like that, regardless of my age i am still a customer and she thought i would let it go. Also i am now left hungry or left to resort to an alternative because something was put on the shelf without being put on the system. its unacceptable and no way my problem<br> <br> Kind Regards
