Treating a customer as ********

One evening i went to Cambridge to buy inkomasi and the store was pretty full. I was in a rush to get home and they was a long to que to get out the store, so the security guard at the door is checking customers items and slips, so as I walk the store the security guard in a very unfriendly rude way calls me back to check my one item, so he pulls me back in a aggressive way like I'm some ******** and when I ask him not to touch me he tore my slip and even worse I still ask him not to touch me he starts searching me after I asked him not to touch me. I've never been treated so disgustingly by another human being in my life and it's not the first time it is happening, I feel like my rights have been violated. I lodged a complaint to managment all they can do is apologise. I'm disappointed and disgusted with the way Cambridge foods treat their customers.
