bad attitude

I was at rage at 13H14 this afternoon to purchase the shoes,the price sticker was R129.00 but when i swiped my card i only saw the slip it was R144.99. I asked to get them for the price i saw the dreadlock lady(XB1) told me she forgot to put the right price, and gave me R15.00 cash back but her attitude was very bad she was even leaning on the counter. Then i had to walk away from the store with a box without any carrier bag.
