Disrespectful security at clicks menlyn park

I experienced very hurtfull ************** at clicks in menlyn from the two security guards, they stopped and asked for my till slip before I even walked through the door and embarrassed me in front of everyone.. Hurtfull because I just paid for an energy drink (1 item) and I had it in hand. Spoke with me like I was nothing In there like I can't pay for my own stuff. I'm hurt very much
