Checkers liquor fourways mall security is unmannered

The security at checkers liquor at fourways mall is so ridiculously unfair and not friendly. How can he say a checkers trolley is not allowed inside. I have bought things at other shops and he soesnt even know what quantities im going to buy he rudely say ama trolley a wa ngeni as if i even speak zulu. I must dare leave my things on the door floor. What foolishness is this, is this the customer service? Whose rule is this that he is rudley actioning. What if my things go missing while sitting on a germ floor?
