Their security labelled me a theif

So i went in on Friday late at the park station pick n pay to buy few things for the weekend. When i got to the door the security guy wanted me to give him the little packet i had. I told him its fish n chips n russian to which he responded so! I asked him u wanna touch my food with ur hands he said yes u people *****. One the packet was a size of my hand so even if us people ***** wat was gonna fit in there two i do not appreciate being label a *****. I have never in my life stole so where does pick n pay get off hiring staff that judge customers? I refuse to be labelled anything worse a *****. I demand an apology from the guy who labelled me a ***** just because he wanted to lay his hands on my food in the name of putting sellotape. Sorry i am not a ***** nor do a resemble one. I am not responsible for pick n pay's botched security system so i do not in one bit appreciate the insult i got on Friday night
