Treated like a ******** at spar bellair

I went to shop at spar belair ,I was treated like a ******** in 2019? . The security guard asked me what's in my bag as I was walking in , few seconds later whilst I was digesting this , a white lady walks in freely without being asked the nonsense I was asked . I'm still shocked in 2019 ? I've been shopping there for more than 5 years , this is appalling .
