Checkers cashiers making us feel small for asking for a cashbsck

I had a worse experience in checkers Rustenburg mall, and it is not the first time were cashiers refuse to give me cash back, she just simply say I don't have it, with a attitude, worse it is like the colude on this thing.

I don't know, maybe when we ask for cashback Checkers take some portion of their salary, because aowa, this people they will make you feel bad for asking for your own money!
