We cant be treated like ********* by Securities after buying

My brother and I were treated rudely and badly by the cambridge food Hillbrow Securities. Thy demanded to search us after buying, we try by all means to keep the Covid 19 protocols and keep safe how many people do they search then demand to search us if not we will be beaten. Our customers right are not being protected by the store. I have visited alot of Cambridge food Stores but have never been subjected to such. Or is it store policy that every customer gets searched after by? But we are being exposed to the pandemic
