Food poisoning

I went to shoprite in Golden Walk,, and we baught fish,, the fish was num it look is like its a rotten fish,, that was rediculous,, I had to go back and ask for a supervisor, the lady when I told her about the incident,, she didn't even bother herself to apologize or to look at the fish,, she's a colored old lady with short hair,,,, she was rude instead of apologize,, all she said is, go to the kitchen and ask you to make you fresh fish,, so that means the one we baught it was not fresh,, she's no professional to work as a supervisor,,, good attitude to the business is more important,,, i think shoprite golden walk they must stop selling food,, coz they sell rotten food,, maybe they need to be told that food is a poison,,
