Disgusting attitude from a supervisor

I went to the Checkers in Glenfair to buy Lip Ice. The price said R14.99 and when I went to the till to pay it rung up as R19.99. So I said no, that's not right, it says R14.99 at the back. The cashier sends someone to go check the price. Next thing I know, the supervisor is there, Mark Jansen van Rensburg, telling me, no I'm wrong, it's the Lip Ice underneath this one that's R14.99. So I say no it's not, let me show you. I go to the shelf where I found the lip ice and show him, look, it's R14.99. He grabs the price, shoves it into the hands of the worker and says, \Just take the price and fix it"before storming off. Then he has an attitude when he has to authorise the price change"
