Discount Foods - Jeppe

Guys I am really irritated,... so I went to discount foods, on Jeppe Street, between Mooi and Polly Street as that where my taxi drops me in the morning. Bought myself lemons, carrots and lemon juice where the sign said the juice is R9. But at the door as I'm going I check my slip and it says the juice is R16.50. I tell the manager and he says they don't so cash refunds. Guys long story short, now I am very angry tell the manager to enjoy the juice and I leave everything there, he says cause people keep returning thing to the shop he does not give a refund. I had no even walked out the door and I he does not know me, first time I even went to that Discount Foods. Well NEVER AGAIN, THEIR SERVICE SUCKS AND THE ARE FULL OF THEMSELVES, what makes them so important that I, Philisiwe Immaculate Sithebe would want to rob or ***** them? Guys I always go shopping at the one on Von WBrandis and I get a service. Jeppe.....
