Derogatory Behavior

I walked into Woolworths today with my mother at about 12pm, we saw the queue and decided to pay the account locally at a shop near us, we were in for not even 10 minutes and nothing was looked at or touched, I had my house keys in my bag over my shoulder and on the way out I set the alarm off, I walked back inside and all we could here was the security guard on his radio saying 2 whiskies at the back entrance, two female whiskies, yes I got them, I repeatedly told him that my keys had set the alarm off and he just kept shouting into his radio at no point did he ask me to check my bag, after telling him 3 times it was my keys, I eventually shouted its my F@#king keys to which he rep**** oh is it your f@*king keys, this is after I had numerous people staring at us, I was embarrassed and felt completely violated not only was he being rude and completely unprofessional he was basically accusing me of *****ing and calling me a whiskey, this is a rainbow nation, I am white, Kumar you need to learn how to do your job and I deeply suggest that woolwothts considers the security people under their employment, I will never step foot into your store again!!!!
