Arrogance of staff member

I went to Village mall today to buy items from Jet, Edgars, Woolworths and Ackersman. I went into the Ackermans shop without being stopped to close my bags. While shopping the person whom is on duty at the door (Ackermans staff member, not a security guard) came to me to say he did not close my bags and will check my bags when I go out (As if I am a ******** infront of all the people), and asking me if I have slips for the items, I said to him this is fine he can check it. After shopping and paying my things he stopped me at the door going through my private things as he wants, I asked him what is he checking as all the items had tags on of the other companies, he said they also sell kids shoes that is what he is checking. After I said to him that is not my fault he does not stop and check the people coming into the shop he said he does not have time to wait for me. THE JOKE IS HE DID NOT EVEN OPEN OR CHECK THE ITEMS I BOUGHT FROM ACKERMANS TO SEE IF IT IS ON THE SLIP, HE DID NOT EVEN ASK FOR THE ACKERMANS SLIP...
